Biotic factors – the effects of living organisms, e.g. Microbes get a supply of energy to stay alive, and the trapped nutrients are recycled. Reproductive cloning generates genetically identical organisms. Intraspecific competition- competition between individuals of the, Interspecific competition- competition between individuals of, Interspecific competition could result in, Important to realise that in the laboratory, it’s, The different sized DNA strands run through the machine (. Module 4 Assessment One Resources available ... Module 6 Mitosis, Meiosis, and Genetics Resources available 3 1.1.1 Electromagnetic The impact of biotechnology on biological diversity is also explored in this module. Many biotechnological processes make use of microorganisms (bacteria and fungi) as they have many advantages: A culture is a growth of microorganisms. However, it is important to remember that many cut plasmids will, in the presence of ligase enzymes, simply reseal to reform the original plasmid. The two main reasons for carrying out genetic engineering are: There are 4 steps of genetic engineering: The gene, one packaged in a vector, can form quite a large molecule that does not easily cross the membrane to enter the recipient cell. The homeodomain on the protein is able to bind to DNA, switching it on or off controlling transcription (the protein is the transcription factor). During limb development apoptosis causes the digits (fingers and toes) to separate from each other. Energy is used for respiration which is lost through heatenergy. The cytoskeleton and the endoplasmic reticulum. Some proteins have to be activated by a chemical, cyclic AMP that, like ATP, is a nucleotide derivative. With no ADP, the cell will not be able to make ATP in which to store the energy from cellular respiration. This is natural selection, the mechanism for evolution. Module 10: DNA Replication. 161-163 Complete: On Your Own 6.1, 6.2… Overview of Week 8’s Inquiry Question – Does artificial manipulation of DNA have the potential to change populations forever? amino acids, proteins, enzymes, nucleic acids, ethanol, lactate. Habitat – the place where an organism lives. Get ready to ace the HSC and get that Band 6 in HSC Biology! Plasmid – a small circular piece of DNA. Module 1 - Cells as the Basis of Life; Module 2 - Organisation of Living Things; Module 3 - Biological Diversity; Module 4 - Ecosystem Dynamics. Selective breeding can be used to increase the productivity of animals. Blog. The most common vectors are bacterial plasmids sealed using DNA ligase. Collect eggs from a high-value female (e.g. The lac operon is a section of DNA within the bacterium’s DNA, consisting of: The regulator gene controls the production of repressor protein. This is a frame holding a number of long needles or pointers. Learning Objective #1 – Investigate the uses and advantages of current genetic technologies that induce genetic change. At the other end of the molecule are three unpaired nucleotide bases, known as an anticodon. There are ethical objections to the use of human embryonic material and some scientific concerns about a lack of understanding of how cloned cells will behave over time. Learn. HOw many ATPs can it make from a molecule of glucose? The human genome consists of about 3 billion nucleotide base pairs. Mutation – a change in the amount of or arrangement of the genetic material in a cell, by base deletion, addition, substitution or by inversion or repeat of a triplet. Predation can act as a limiting factor on a prey’s population size. Unwanted microorganisms: (a) explain the significance of limiting factors in determining the final size of a population. Biology Module 6 – Genetic Change Contents 1.0 Mutation . 6.1.1 Cellular control Sample Cards: describe the 3 types of mutation that ca, what effects can genetic mutations have, what are the causes of mutations 4 20 Cards Preview Flashcards Revision Notes for A-Level OCR Biology A. Even so, the process is very inefficient – less than a quarter of 1% of bacterial cells take up a plasmid. Module 8: Membrane Transport. Competition occurs when resources(like food or water) are not present in adequate amounts to satisfy the needs of all the individuals who depend on those resources. This is a summary note of OCR Biology A Module 6 Genetics, Biotechnology and Cloning Exam Question and Answer (New Spec). What information can we decipher from It can also be useful for measuring the height of plants. Mutations with Harmful or Beneficial Effects: Early humans in Africa almost certainly had dark skin. The apoptosis process occurs very quickly. In this article, we cover the tree topics for Module 6: Genetic Change for Year 12 Biology. However, they could still synthesise vitamin D from the action of the intense sunlight on their skin. Without genetic mutations there would be not evolution. Non-reproductive cloning generates cells, tissues and organs – can replace those damaged by diseases or accidents. Recover the early embryo and implant the embryo in surrogate mother ewe’s uterus. ATP supplies a package for the energy produced in cellular respiration. Comparing genes and regulatory sequences of different organisms will help us to understand the role of genetic information in a range of areas including health, behaviour and evolutionary relationships between organisms. The recipient cell expresses the gene through protein synthesis. Biology: Module 7. Module 7: Lipids and Membranes. What make it possible for the plasma membrane to self-assemble? The polymerase chain reaction is basically artificial DNA replication. DNA ligase then seals the sugar-phosphate backbone. Clones – genes, cells or whole organisms that carry identical genetic material because they are derived from the same original DNA. It contains past exam questions (Old & New Spec) and its answers below. (h) discuss the economic, social and ethical reasons for conservation of biological resources, (i) outline, with examples, the effects of human activities on the animal and plant populations in the Galapagos Islands. Nitrogen is needed to make proteins and nucleic acids. It includes summary notes I used for my A level revision last school year. (d) explain, with examples, the terms interspecific and intraspecific competition. Spell. geraniums, a section of the stem is cut between leaf joints (nodes). Do you have any questions for me at this time? The DNA polymerase enzyme is described as ‘thermophilic’ because it is not denatured by the extreme temperatures used in the process. There are two types of lipoprotein: high-density lipoproteins (HDL) and low-density lipoproteins (LDL). food supply, predation, disease, competition. The advantage to the bacteria of conjugation is that it may contribute to genetic variation. Fewer prey now eaten = prey population increases. In 2003, it was reported that pigs engineered to lack the enzyme α-1,3-transferase had been successfully developed. 3 1.1 Mutagens . Succession – a change in a habitat causing a change in the make-up of a community. Plasmids are found in many types of bacteria and are separate from the main bacterial chromosome. Just deal with the process after the product is made. Apoptosis is tightly regulated during development, and different tissues use different signals for inducing it. Primers – short, single stranded sequences of known bases (around 10-20 bases in length), that are the ‘starting point’ for DNA polymerase to bind – DNA polymerase enzymes cannot bind directly to single-stranded DNA. Methods used to get the vector into the recipient cell include: Enzymes known as restriction enzymes (restriction endonucleases) are used to cut through DNA at specific points. Test. It weeds out ineffective or harmful T lymphocytes during the development of the immune system. A cell contains centrioles and lysosomes. Click on the white circle connected to an organelle to see the name and function.Very simple and easy to understand. You stretch a tape measure across the habitat and take samples along the line. Commercial applications of biotechnology often require the growth of a particular organism on an enormous scale. Nitrogen gas is very unreactive, so is impossible for plants to use it directly. In 2006, scientists reported that engineering of the human nucleotidase enzyme (E5’N) into pig cells in culture reduced the active of a number of immune cell activities involved in xenotransplant rejection. You could: A point quadrat may be used. Match. Get our latest COVID-19 advice. Allele – an alternative version of a gene. high yields, disease resistance or pest resistance) to reproduce together in order to increase productivity. Learn with flashcards, games, and more — for free. Homeobox genes – regulatory genes that codes for proteins that controls the development of body plans. The limiting factors may include food, water, light, oxygen, shelter, predators,parasites, intensity of competition within and between species etc. Population – all of the organisms of one species , who live in the same place at the same time, and can breed together. Some organisms have more Hox clusters than others. The enzymes digest the material into small molecules, which are then absorbed into the organisms body. Split the embryo into several separate segments and implant into surrogate mothers. More prey = predator numbers increase and the cycle begins again. It is therefore transported in the form of lipoproteins (tiny balls of fat combined with protein). If a cell has no oxygen, what stage(s) of aerobic cellular respiration can still run? The well-adapted organisms can out-compete those in the population that do not have the advantageous characteristics. Radioactive marker – the location can be revealed by exposure to, Fluorescent marker – emits a colour on exposure to, It was found that only mice infected with the S-strain were killed by a protein that was, Augmentation (adding genes) – applies to conditions that are caused by, Killing Specific Cells – e.g. These proteins bind to apoptosis inhibitor proteins and allow the process to take place.

Module 6: Genetics, Evolution and Ecosystems. In adults, 50-70 million cells per day undergo apoptosis. The enzyme is derived from a thermophilic bacterium, Thermus aquaticus (Taq), which grows in hot springs at a temperature of 90oC. very large cows. 1 BIOLOGY 2B03 Cellular Biology Module 6: Cell signaling Lecture 1: Concepts in signaling Objectives • Describe signaling absorption, digestion, respiration, biosynthesis, excretion, egestion, secretion, movement, irritability, homeostasis, and reproduction, The plasma membrane is composed of phospholipids, cholesterol, and proteins. Plants need fixed nitrogen as ammonium ions (NH4+) or nitrate ions (NO3). We do not eat lipoproteins, but our diet has a significant effect on the lipoprotein concentration in our blood. A habitat cannot support a population larger than its carrying capacity because of the limiting factors, which place a limit on population size. Biotechnology – the industrial use of living organisms (or parts of living organisms) to produce food, drugs or other products. The nutrient medium in which the microorganisms grow could also support the growth of many unwanted microorganisms. Log (exponential) phase – population size. They are found in cell membranes to improve stability and used to make steroid sex hormones and bile. That includes; cellular control patterns of inheritance manipulating genomes cloning and biotechnology ecosystems and populations and sustainability. Having been absorbed, the molecules are stored or respired to release energy. Vegetative propagation is form of asexual reproduction of a plant. Different food chains join together to make a food web, which helps us understand how energy flows through the whole ecosystem. Apoptosis is controlled by a diverse range of cell signals, including cytokines made by cells of the immune system, hormones, growth factors and nitric oxide. The egg then goes through the stages of development using genetic information from the inserted nucleus. The production of secondary metabolites usually begins after the main growth period of the organisms – does not match the growth in population of the organism. However, maintaining biodiversity in dynamic ecosystems requires careful management. Module 6: Protein Function – Binding and Catalysis. A differentiated cell from an adult can be taken, and its nucleus placed in an egg cell which has had its own nucleus removed (enucleated cell). 2.1 7.1 – Explain how a range of mutagens operate, including but not limited to:. Contents. Abiotic factors– the effects of non-living components, e.g. – by NakedScientists (2011) 7.6.2 – DNA extraction – by Genetic Science Learning Centre (2013) 7.6.3 – Gel Electrophoresis – by Genetic Science Learning Centre (2013) 7.7.1 – Genetics 101 (Part 3 of 5): Where do your genes come from? Protons are released into the cytosol. cancers, genetic techniques can be used to make, Using cloned cells is less likely to be dangerous than a, Basal sprouts (root suckers) – the suckers grow from, Taking Cuttings – e.g. There are 57 lessons in the HSC Study Lab Year 12 Biology course, which corresponds to the 120 indicative hours of study required by the syllabus. DNA probe – a short single-stranded piece of DNA (around 50-80 nucleotides long) that is complementary to a section of the DNA being investigated. If the rates are not balanced: Cell signalling plays a crucial role in maintaining the right balance. A cell begins running low on food, and its energy output decreases by 20%. Because of this, there is less living tissue (biomass) at higher levels of a food chain. The production of primary metabolites matches the growth in population of the organism. Mutations cause changes to the sequence of nucleotides in DNA molecules. What helps the cell hold its shape if it does not have a cell wall? The syllabus, assessment and reporting information and other support materials for the Biology course. Copyright © 2018 Department of Education All Rights Reserved Design by ICT Division Useful in checking your knowledge. Gene Therapy – adding new alleles to the DNA of cells to treat genetic disorders – we are only able to treat recessive disorders. Apoptosis – programmed cell death that occurs in multicellular organisms. Vitamin A (retinol) in the diet only comes from animal sources. A balanced diet is a diet that contains appropriate amounts of all necessary nutrients required for healthy growth and activity. Cyclic AMP activates proteins by altering their three-dimension structure, so that their shape is a better fit to their complementary molecules. The differences between PCR and natural DNA replication include it can only replicate relatively short sequences of DNA (not entire chromosomes), the addition of a primer molecules (to start the process) and PCR involves a cycle of heating and cooling to separate and bind strands. Module 12: RNA Translation-Protein Synthesis. However, there are some ethical issues concerning whether cloning should be used in humans. Transfer RNA (tRNA) – lengths of RNA that fold into hairpin shapes and have three exposed bases at one end where a particular amino acid can bind. Study Owen Bradley's Biology module 6 flashcards now! When together, there was competition for food, with Paramecium aurelia obtaining more food effectively than Parameciumcaudatum, resulting in Paramecium caudatum dying out and the numbers for Paramecium aurelia increasing, eventually becoming the only species remaining. With human population getting larger and expanding exponentially, it is putting pressure on our resources. (b) explain the meaning of the term carrying capacity, (c) describe predator-prey relationships and their possible effects on the population sizes of both the predator and the prey. It explores the application of biology and its significance in finding solutions to health and sustainability issues in a changing world. In animals, only embryonic cells are naturally capable of going through the stages of development in order to generate a new individual. NESA is regularly updating its advice as the coronavirus outbreak unfolds. These have been made according to the specifications (H020, H420, H021, H421) and cover all the relevant topics for examination in May/June. It was found that insertion of two genes into the rice genome was needed in order for the metabolic pathway to create beta-carotene to be activated in the endosperm cells. What organelle is responsible for breaking polysaccharides into monosaccharides. Comparative gene mapping – knowing the sequence of bases in a gene of one organism and being able to compare genes for the same (or similar) proteins across a range of organisms. To join isolated fragments of DNA, an enzyme known as DNA ligase catalyses the condensation reaction that joins the sugar-phosphate backbones of the DNA double helix together. How does a plant cell fight osmosis in a hypotonic solution? Biology Module 6 (Study Guide Questions) STUDY. Module 6: Genetics, Evolution and Ecosystems; AQA. Biology Syllabus p.51 What are the 11 major tasks cells must perform? The enzyme catalyses the hydrolysis reaction that breaks the sugar-phosphate backbones of the DNA double helix. Totipotent – stem cells capable of differentiating into any type of adult cell found in the organism. Gene – a length of DNA that codes for one or more polypeptides, including enzymes. Module 6: Genetic Change. The growing conditions in it can be manipulated and controlled in order to ensure the best possible yield of the product. Individuals within a population who have a certain characteristic may be better adapted to the new environment. The Biology Stage 6 Syllabus explores the diversity of life from a molecular to a biological systems level. Flashcards. Content Focus Topic 1: Mutation Topic 2: Biotechnology Topic 3: Genetic Technologies Content Focus for HSC Biology Module 6: Genetic Change. This is an important source of vitamin D, because much of the food that humans eat contains very little vitamin D. The Inuit people have not lost all their skin pigments, although they do not live in an environment that has intense sunlight. It eventually forms a plaque, which sticks out into the lumen of the artery, leaving the artery wall rougher and less flexible as well as creating a narrower lumen, reducing blood flow. There are two methods of artificially cloning animals: Cells from a developing embryo can be separated out, with each one then going on to produce a separate, genetically identical organism. Mrs. Carter's Biology Class. Homeobox genes each contain a sequence of 180 base pairs (homeobox) coding for the homeodomain. A phospholipid has two fatty acid molecules and a small molecule with a phosphate group, whereas a normal lipid just has 3 fatty acid molecules. They secrete enzymes onto dead and waste material. Biology: Module 6. Module 5: Amino Acids and Proteins. Central vacuole that expands as the cell absorbs water. 7.6.1 – How does DNA Fingerprinting Work? Genomics – the study of the whole set of genetic information in the form of the DNA base sequences that occur in the cells of organisms of a particular species. We are an organization comprising of the most qualified, experienced and passionate HSC teachers/markers whose mission is to help students achieve the best in their final years of schooling. The work of scientists in various fields of work, including agriculture, industry and medicine, can be explored within the context of biotechnology. When a current is applied, charged molecules are attracted to the oppositely charged electrode. Although wildly employed in experimental animals, germline gene therapy in humans is illegal and ethically unacceptable. The first animal cloned by this method was Dolly the sheep in 1996, which was successful after 277 attempts. The energy is stored in dead organisms and waste material which can only be accessed by decomposers. PLAY. Population size = mean no. Neet 2020, Neet 2021, Allen test, Allen pdf, Medical exam, medical college, Jee, studypedia, Terms in this set (17) Name the organelles that play a role in biosynthesis. Niche – the role that each species plays in an ecosystem. cell theory, metabolism, and plant biology Module 1 Organisms, Nutrients and Digestion Resources available Module 2 Cell Theory Resources available. Genome – all the genetic information within an organism OR all the genetic information within an individual. In addition, note the net number of ATPs that are made in each step. Unfortunately, in the plant of the plant that is eaten – the endosperm (grain) – the genes for beta-carotene production are switched off. ribosomes, smooth ER and rough ER, Golgi bodies,chloroplasts, leucoplasts, nucleus. If a gene is altered by a change to its base sequence, it becomes another version of the same gene – an allele. Bacteria is involved in the recycling of nitrogen. For example, if a predator’s population size goes up, the population size of the prey will go down. Biology module 5 and 6 guide (docx 113.95 KB) Module 5 reproduction unit of work (docx 48.97 KB) Genetic variation and human evolution resource (pdf 142.96 KB) Module 7 guide (docx 98.27 KB) Module 7 infectious disease assessment task (docx 49.76 KB) Module 7 … The course examines the interactions between living things and the environments in which they live. Notes. The deposits (atheromas) include cholesterol from low-density lipoproteins (tiny balls of fat and protein that are used to transport cholesterol around in the blood), fibre, dead blood cells and platelets. Module 3 Plant Biology Resources available. LDLs are associated with greater deposition in the artery walls so is best to maintain a low proportion of LDLs. You lower the frame into the quadrat and record any plant touching the needles. Primary metabolites – substances produced by an organism as part of its normal growth, e.g. Remove an ovum (egg) from Scottish Blackface and remove the nucleus to produce an enucleate ovum. Continue those over several generations until cows with very high eat yields are produced, e.g. Conservation is the maintenance of biodiversity, including diversity between species, genetic diversity withinspecies, and maintenance of a variety of habitats and ecosystems.Conservation is a dynamic process involving management and reclamation. Industrial-scale fermentations can be operated in two ways: Metabolites – the products of metabolism (the sum of all of the chemical reactions in an organism), e.g. temperature, pH of soil, soil type, light intensity, oxygen concentrations, carbon dioxide concentrations. Substrate molecules can bind to the enzyme molecules and the products formed go back into the reaction mixture leaving the enzyme molecules in place. Is it a plant or animal cell? Children between the ages of 8-14 years, 20-30 billion cells per day undergo apoptosis. The development of automated sequencing has led to a rapid increase in the number of organism genomes sequenced and published in recent years. Wile, Exploring Creation with Biology 2nd Edition, Name the organelles that play a role in biosynthesis, ribosomes, smooth ER and rough ER, Golgi bodies,chloroplasts, leucoplasts, nucleus. View Biology Module 6- Genetic.pdf from BIOLOGY HTL4150 at University of Technology Sydney. Rice plants (Oryza sativa) contain the gene that code for the production of beta-carotene. The pigment melanin protected from the harmful effects of ultraviolet light. Until the early 1980s, insulin was extracted from the pancreatic tissues of slaughtered pigs, which is not identical to human insulin, is less effective and very expensive to produce, since only a very small amount of insulin is present in pancreatic tissue. It’s important to choose the right size of the quadrat (normally 50cm or 1m quadrats are used) depending on the size of the area. Wile, Exploring Creation with Biology 2nd Edition. The endothelium (inner lining) of the artery can become damaged. They are both released into the blood and can be taken up by cells that have the correct receptor sites. Ecosystems are dynamic systems because the population rises and falls due to the interactions of living organisms between each other and with the physical environment. Lesson 2 | Types of mutations. Although Genetic Change may seem like a short module, it focuses on a few, complicated concepts. What is the difference between a phospholipid and a regular lipid? As oxidation requires oxygen, these reactions only happen in well-aerated soils.
