Substitution of a base occurs but same amino acid is coded for. – Conservation of nearly extinct species e.g. This suggests that the two chromosomes may have fused together somewhere in evolutionary lineage. E.g. The gene cascade for skeletal and neurological development in limbs is also a homologue. Overcomes geographical barriers, allowing genes to be spread worldwide. William James Farrer, born in the UK in 1845, travelled to Australia in the 1880s and began a selective breeding program to develop a better variety of wheat. 161-163 Complete: On Your Own 6.1, 6.2… But functionally, most SNPs will not create a whole new functional phenotype of the gene product. The syllabus, assessment and reporting information and other support materials for the Biology course. DNA segments are then transferred to a nylon sheet through southern blotting, and radioactive dyes or coloured probes are added to produce banding patterns characteristic of the DNA fingerprint when exposed to X-rays. Transposons were discovered in the 1940s by Barbara McLintock in her study of the pigment variations in Indian corn. bacteria gaining resistance). Homeotic genes are found in most groups of multicellular animals and show similar DNA sequences, suggesting that these genes evolved from a common ancestor. HSC Biology tutoring at Dux College provides students with the right support to achieve a band 6 result in HSC Biology. Higher yield, larger fruit and disease resistance. In step 5 the plasmids enter the bacteria in 1 of 2 ways: i) Heat shock: Bacterial cells + recombinant plasmids + non-recombinant plasmids placed in cold solution → rapidly increase temperature → bacteria cell membrane is disrupted → plasmids enter bacteria. Overview of Week 14 Inquiry Question – Do non-infectious diseases cause more deaths than infectious diseases? E.g. They can be put into a solution and dripped into the lung through a thin tube. Tissue, bone, muscle, nerves and blood vessels must also develop in the correct order. Substitution of a base occurs but different amino acid is coded for. muscular dystrophy. The production of the transgenic BT cotton plant has allowed humans to grow cotton plants resistant to the caterpillar Helicoverpa. Digestion. ovaries, testes). Transposable element: short DNA sequences that. Cloning embryonic stem cells (unspecialised cells but can differentiate into specialised cells) for the treatment of disease. Farmers do not have to maintain cost and health of a male animal health since they just need sperm. Many plants and animals for domestic and agricultural purposes have been bred in this way to produce new varieties. Early embryo is split in two → embryos put in a surrogate mother. If you want to do well in Chemistry or Physics, you really need to know your facts and provide detail – especially when you get slapped with a 6-7 mark question (for example the soap or CFC question in the 2016 HSC Chemistry exam paper). – Cause errors in replication and chromosome duplication. Mendel also observed two characteristics at one time in plants. Huntington’s disease, earlier detection of genetic predispositions to disease e.g. 1. Other uses: production of human growth hormone, protein that dissolves blood clots (heart conditions), bacteria to break down toxic waste in oil spills, pest resistance in some plants (e.g. Please. Heredity study session. Modifier les données. The correct sequence in the cascade is necessary for the correct limbs developing in the correct parts of the body. HSC Biology Module 5: Heredity - Dux College Aligned to the New AP Biology 2019 Course and Exam Description!Review Page 7/27. Proteins include enzymes, hormones and structural proteins in cell membranes, all of which control chemical reactions and cell activities, and thus determine the characteristics of organisms. The mixture is allowed to cool a little to allow primers to bind to the ends of the genes. Module 7 | Infectious disease Content 3: Immunity Lesson 1 | Innate and adaptive immune system. 0 Replies 6071 Views: January 17, 2017, 09:58:52 pm by jamonwindeyer: Practical experiments and investigation related questions. For example, mutations causing skin cancer due to UV radiation affect only the individual but not the whole population. plants for nurseries and food, Lack of diversity – risk of extinction from new strain of disease or an environmental change, Uncertain – which characteristics are inherited, Certain – the new organisms is identical to the parent, except for environmental factors affecting gene expression, early-ripening, drought tolerance, short straw, more grains per stalk, good baking and milling quality, stiff straw, late maturing, early-ripening, drought tolerance, short and stiff straw, reasonable baking quality, susceptible to drought, late-maturing, soft for baking, high yield, early-ripening, drought tolerance, short and stiff straw, good brown heads, good baking quality, good yield, DNA in the area of the gene unwinds and unzips, assisted by DNA helicases. Complicating things, it is often the Module that students get the least time with during the HSC year. Fertilisation: random fusing of genetically recombined gametes during fertilisation increases genetic variation. Meet Your HSC Biology Bounce Back … An egg cell is taken from an adult donor and its nucleus destroyed by UV radiation (, The nucleus from the udder cell is inserted into the enucleated egg cell with a. DNA fingerprinting involves comparing DNA patterns of different fragments of different individuals.

Terms in this set (62) Absorption. These transposons may explain why bacteria develop resistance to antibiotics so rapidly, therefore influencing the bacterial genome. Gene rearrangements on chromosomes result in mutations: Chromosomal mutations can occur during meiosis as a result of homologous pairs of chromosomes not separating during the first division (non-disjunction). Assessment Task Case Study Essay Half Yearly Paper Study Notes Past HSC Questions Past Trial Papers. HSC Study Notes » Chemistry Study Notes Find the Study Notes you need. pollen blown to a new area. In the previous Module 1: Cells as the Basis of Life, you would’ve been looking at the microscopic features of cells. Year 11 Biology Sign up now $99 / year. File Type PDF Study Guide Heredity and study resources for Heredity and Genetics. HSC All Subjects New Curriculum and Syllabus 2020-21 Latest Approved by NCTB.NCTB stands for National Curriculum and Textbook Board (NCTB). Gene regulation may also take place by shortening the life of the mRNA so that protein synthesis is stopped by removal of the protective caps. Recombines DNA between population = increases gene pool. Interestingly, the banding patterns between the human number 2 chromosomes and each pair of smaller chromosomes in the other primates are very similar, and humans have fewer chromosomes than these primates. This is a set of HSC Biology dot-point summary notes for the Option Topic – Genetics: The Code Broken. Content 1 Content 2 Content 3 Content 4 Content 5. The goals were to: These goals have mostly been achieved, the project was a success. Other examples of polygenic inheritance: skin colour in humans, colour in wheat kernels, egg weight in poultry, fleece weight in sheep. Module 7. Get our latest COVID-19 advice. Recombinant DNA technology makes synthetic enzymes e.g. Selective breeding: Mule was bred from the female horse and male donkey. Thus different results are produced: If crossing over occurs and genes undergo recombination, recombinant offspring may be produced alongside the parental types. In humans, transposons have been linked with antibody production and some rearrangements by transposons are believed to cause certain cancers. This way, the mistake is not present in other cells produced by mitosis of the mutant cell. Cystic fibrosis is caused by a single faulty CFTR gene (autosomal recessive inheritance) unable to produce a functioning protein to regulate the way chloride ions enter cell membranes. NESA is regularly updating its advice as the coronavirus outbreak unfolds. It is the syllabus’ effort in putting a greater focus on genetics and genetic techniques when, previously, genetics didn’t have such a dedicated section. Injection of sperm into an egg using a pipette. This is being enhanced by the Human Genome Project that has sequenced the entire human genome to identify all the encoded genes. GM crops can reintroduce genes that have died out → increases gene pool. in non-coding DNA, or still producing the same amino acid) or beneficial (e.g. A chromosome map shows the relative positions of genes on a chromosome. In a cross breeding experiment, ABC was crossed with abc and the percentages of recombination were observed. Sign up « Back to subjects. *Note: we’ve received feedback that there is conflicting information about whether there is in fact different defined alleles within the Rhesus phenotype. This simple binary view of the Rhesus phenotype can sometimes be insufficient. Changes nucleotide sequence of chromosome = incorrect functioning. Cell Replication. Animals that appeared earlier in geological history have a small number of homeotic genes than more recently evolved groups. The syllabus, assessment and reporting information and other support materials for the Biology course. E.g. How to use HSC Study Lab in your classroom; Contact us; 0. 3. The new HSC is here, and you’ve got to study it. Genetic abnormalities in embryos can be identified leaving parents with the choice to terminate pregnancy. This may involve folding, cleavage or the addition of non-protein sections such as carbohydrates or lipids. Sign up « Back to subjects. The breakdown of food molecules with a release of energy. Get our latest COVID-19 advice. His first variety, called Bob’s variety, was directly derived from Blount’s Lambrigg, a named given by Farrer to an outstanding wheat from Professor Blount’s Hybrid No.38, Gypsum. The Human Genome Project was completed in 2003, a collaborative project that lasted 13 years. The analysis of similarities and difference genomes supports this fact. Gene cloning is when multiple copies of an identical gene are produced. The transport of dissolved substances into cells. HSC Study Notes » Chemistry Study Notes Find the Study Notes you need. The turning on and off of genes in a particular order is crucial for normal development. But if they were linked in both parents as BG/bg, there would only be two possible gametes: BG and bg. Transposable genetic elements (also called transposons) are sections of DNA that are not fixed and can move around among chromosomes. Organisms that are closely related and diverged from a common ancestor recently will have similar genes. The difference between the genomes is about 4%, including about 35 million single nucleotide differences 90 million base pairs of insertions and deletions. It may have included cell structures like organelles and biochemical processes. Module 5 - Heredity. These may be required for DNA fingerprinting, producing transgenic species, gene therapy, locating the position of a gene on a chromosome or for producing chemicals such as human insulin. The single strands from each organism are mixed and allowed to bind where the bases match. Great news — the new changes to Year 11 Biology Module 2: Organisation of Living Things makes it EASIER to understand Biology! Flashcards for Study Guide for Module #6 in Exploring Creation with Biology 2nd Edition. Polymerase chain reaction produces many copies of a gene.

Heterozygous blood type A/Heterozygous blood type B, IAIB: IAi: IBi: ii = AB: A: B: O = 1:1:1:1, Heterozygous Rhesus positive/Rhesus negative. Inheritance involves multiple alleles when a characteristic is determined by more than 2 alleles for a particular gene that can be present within a population. 1 Module 7: Infectious Disease. There are two types of genes involved in embryonic development. browse Study NOTES. The length of each fragment depends on the individual so the segments are sorted by size by a sieving process of electrophoresis in a gel. ii) Asexual reproduction: Regeneration e.g. NSW Department of Education. Receive study guides, note, exam tips and bits of wisdom from our tutors each month. Aquatic → terrestrial = external fertilisation → internal fertilisation. Outcomes are coded and linked to content. For proteins that don’t do highly conserved enzymatic functions etc., like RHD, there will probably be more. Dr Silvia Rudmann goes over some exam tips and gives advice on how to improve your marks in the HSC Biology exam in this Aurora College recording. Heredity study session. Cattle with more beef or higher milk production. Copyright © Dux College Pty Ltd. All Rights Reserved | Privacy Policy, We are currently conducting in-person teaching at our centres, as well as online classes. This increases viable yield and protects the cotton industry, as previously the pest destroyed hundreds of millions of dollars’ worth of cotton each year. Patenting: Companies control/own biotechnologies → companies can control prices of biotechnologies and make them unaffordable → social inequality. PCR allows 100 billion copies of a DNA section to be produced in a few hours. When the bacterial cell reproduces, many copies of the plasmid and hence the human insulin gene are produced. Mutation: somatic or germ line mutation introduce new alleles. Before Farrer’s and Guthrie’s varieties were grown, Australia’s wheat industry suffered greatly due to rust fungus. Module A – How to write a Band 6 Essay. But Farrers ‘strong’ wheats did not yield as well as older types, such as Purple Straw, when disease was not a problem. Study Notes. Genetic drift: random change in allele frequency by chance (unlike natural selection which is not based on chance but on which alleles are most favourable). Wheat harvest was sometimes so poor that tough wheat from the US had to be imported. In addition, genes mapped through linkage maps must code for an observable characteristic, but the vast majority of human DNA is non-coding and would lead to no observable feature or function. The degree of bonding reflects the degree of similarity. HSC Book PDF Guide new version is available . Dux College understands that writing Band 6 Module A essay’s can be challenging. Breeding Fresian dairy cows → higher milk production. Selective breeding can alter the combination of genes and the frequency of genes in a gene pool but does not introduce new genes. Start by filtering Study Materials by Subject, Resource type, Grade & Date. At this time, Farrer and Guthrie were already developing their superior varieties of wheat, but these were not accepted by farmers. No observable effect (since same amino acid). As each individual has a unique DNA profile (except identical twins), DNA fingerprinting allows exclusive identification of an individual. Year 12 Biology Sign up now $99 / year. Analysis of genes provides evidence to accurately determine evolutionary relationships between a variety of species. Driven By Results. Search. after the next tRNA comes in, the first one leaves to be reloaded, Different coloured pegs – different bases, Threading objects onto ribbon – covalent bonds. Sommaire principal. NESA is regularly updating its advice as the coronavirus outbreak unfolds. Somatic cells are body cells. E.g. This process was used to make bread, wine and cheese. Hence the location of a gene on a chromosome can be determined. mRNA is modified so that it consist only of the base sequence that will code for the polypeptide (introns cut out, exons kept in). 1500AD corn was large with lots of kernels due to selective breeding. Introduces new alleles which enter the gene pool = increases gene pool. Content 1 Content 2 Content 3 Content 4. – Beef and dairy cattle have been cloned to increase food production in agriculture e.g. By selecting individuals that combined the advantages of both, they developed Comeback, an improvement on Bob’s variety. A protein produced by one gene can also turn another off. This could be important clinically if blood from ‘weak D’ donors is transfused into a Rh- patient. Although many characteristic features, such as a broad face and short stature, are shared between individuals with Down Syndrome, they are all unique and the extent of intellectual retardation varies. When transposons ‘jump’, they can copy themselves and leave a copy in the original position, or completely jump to a new place in the genome. Delivery of the gene by using a modified virus is also being trialled. However there has been a decrease in fertility of cattle and horses since the introduction of this technology. This is important in the differentiation of cells. Adds 1 or 2 nucleotides and pushes all proceeding nucleotides out of order. … Non-infectious disease and disorders. Germ line mutations occur in cells that produce gametes (e.g. Regulatory proteins control the splicing. NESA | NSW Education Standards Authority. or “centiMorgan” (cM), and corresponds to the percentage of recombinant offspring produced in a test cross between the offspring of a pure breeding parent showing dominant characteristics and a parent with recessive characteristics, and an organism with recessive characteristics i.e. If these dimers are formed and affect in the DNA sequence of the following genes, skin cancer can develop if the dimers are not repaired by repair enzymes in our cells. A mutagen is a physical factor of chemical substance that causes mutations. Tim Sloane gives an overview of genetic change (module 6) in this Aurora College recording. Content 1 Content 2 Content 3. Assess the significance of ‘coding’ and ‘non-coding’ DNA segments in the process of mutation. Selective breeding involves human selection of two individuals with desirable characteristics to mate, with the hope that the offspring will inherit these desirable characteristics. The gene coding for haemoglobin has evolved from the gene coding for myoglobin. They include high energy radiation, and chemicals such as mustard gas, Agent Orange and hydrocarbons in cigarette smoke. The length of each fragment depends on the individual so the segments are sorted by size by a sieving process of electrophoresis in a gel. Reproduction. – Introduce new alleles into a population = natural selection. A pprendre les M aths sur I nternet. Year 12 Biology. HSC Biology Module 5: Heredity and the start of Year 12 Biology is a sharp twist towards genetics and more complex ideas about health and disease. Analysis of genes can also disprove previous evolutionary trees drawn based on structural characteristics. Bookings for Term 3 school holidays 28/9 to 9/10 are OPEN: ‍ Module 5: Heredity - aimed at students starting year 12 in Term 4. Transposons result in new chromosomal rearrangements, which can change the way genes are expressed, increase variety and play a major role in evolution. Contents. Describe the evidence which indicates the presence of ancestral vertebrate gene homologues in lower animal classes, Discuss the evidence available from current research about the evolution of genes and their actions, Identify data sources, gather, process and analyse information from secondary sources and use available evidence to assess the evidence that analysis of genes provides for evolutionary relationships, Genes code for antigens on the surface of blood cells, Does it involve simple dominant-recessive inheritance, Yes: D dominant over d, C over c and E over e, Production of genetically identical copies of a single gene, Production of identical copies of an organism (identical genome), Recombinant DNA technology or polymerase chain reaction, SCNT, cuttings, bulbs, runners, tissue culture, Single genes for analysis e.g.
