Covers: (b) Inheritance 3.14 understand that the genome is the entire DNA of an organism and that a gene is a section of a molecule of DNA that codes for a specific protein 3.15 understand that the nucleus of a cell contains chromosomes on which genes are located 3.16B describe a DNA molecule as two strands coiled to form a double helix, the strands being linked by a series of paired bases: adenine (A) with thymine (T), and cytosine © with guanine (G) 3.17B understand that an RNA molecule is single stranded and contains uracil (U) instead of thymine (T) 3.18B describe the stages of protein synthesis including transcription and translation, including the role of mRNA, ribosomes, tRNA, codons and anticodons 3.19 understand how genes exist in alternative forms called alleles which give rise to differences in inherited characteristics 3.20 understand the meaning of the terms: dominant, recessive, homozygous, heterozygous, phenotype, and genotype 3.21B understand the meaning of the term codominance 3.22 understand that most phenotypic features are the result of polygenic inheritance rather than single genes 3.23 describe patterns of monohybrid inheritance using a genetic diagram 3.24 understand how to interpret family pedigrees 3.25 predict probabilities of outcomes from monohybrid crosses 3.26 understand how the sex of a person is controlled by one pair of chromosomes, XX in a female and XY in a male 3.27 describe the determination of the sex of offspring at fertilisation, using a genetic diagram 3.28 understand how division of a diploid cell by mitosis produces two cells that contain identical sets of chromosomes 3.29 understand that mitosis occurs during growth, repair, cloning and asexual reproduction 3.30 understand how division of a cell by meiosis produces four cells, each with half the number of chromosomes, and that this results in the formation of genetically different haploid gametes 3.31 understand how random fertilisation produces genetic variation of offspring 3.32 know that in human cells the diploid number of chromosomes is 46 and the haploid number is 23 3.33 understand that variation within a species can be genetic, environmental, or a combination of both 3.34 understand that mutation is a rare, random change in genetic material that can be inherited 3.35B understand how a change in DNA can affect the phenotype by altering the sequence of amino acids in a protein 3.36B understand how most genetic mutations have no effect on the phenotype, some have a small effect and rarely do they have a significant effect 3.38 explain Darwin’s theory of evolution by natural selection 3.39 understand how resistance to antibiotics can increase in bacterial populations, and appreciate how such an increase can lead to infections being difficult to control

By the end of the powerpoint students would have covered: 4.5.2.2 The brain (biology only) The brain controls complex behaviour. It is made of billions of interconnected neurones and has different regions that carry out different functions. Students should be able to identify the cerebral cortex, cerebellum and medulla on a diagram of the brain, and describe their functions. (HT only) Students should be able to explain some of the difficulties of investigating brain function and treating brain damage and disease. (HT only) Neuroscientists have been able to map the regions of the brain to particular functions by studying patients with brain damage, electrically stimulating different parts of the brain and using MRI scanning techniques. The complexity and delicacy of the brain makes investigating and treating brain disorders very difficult.

By the end of the powerpoint students would have covered: **4.5.3.1 Human endocrine system ** Students should be able to describe the principles of hormonal coordination and control by the human endocrine system. The endocrine system is composed of glands which secrete chemicals called hormones directly into the bloodstream. The blood carries the hormone to a target organ where it produces an effect. Compared to the nervous system the effects are slower but act for longer. The pituitary gland in the brain is a ‘master gland’ which secretes several hormones into the blood in response to body conditions. These hormones in turn act on other glands to stimulate other hormones to be released to bring about effects. Students should be able to identify the position of the following on a diagram of the human body: pituitary gland pancreas thyroid adrenal gland ovary testes. Contains examination questions

Traditionally drugs were extracted from plants and microorganisms. • The heart drug digitalis originates from foxgloves. • The painkiller aspirin originates from willow. • Penicillin was discovered by Alexander Fleming from the Penicillium mould. Most new drugs are synthesised by chemists in the pharmaceutical industry. However, the starting point may still be a chemical extracted from a plant. New medical drugs have to be tested and trialled before being used to check that they are safe and effective. New drugs are extensively tested for toxicity, efficacy and dose. Preclinical testing is done in a laboratory using cells, tissues and live animals. Clinical trials use healthy volunteers and patients. • Very low doses of the drug are given at the start of the clinical trial. • If the drug is found to be safe, further clinical trials are carried out to find the optimum dose for the drug. • In double blind trials, some patients are given a placebo.

Limited to the differences in magnification and resolution. An electron microscope has much higher magnification and resolving power than a light microscope. This means that it can be used to study cells in much finer detail. This has enabled biologists to see and understand many more sub-cellular structures. Students should be able to carry out calculations involving magnification, real size and image size using the formula: magnification = size of image size of real object Students should be able to express answers in standard form if appropriate. Required practical activity 1: use a light microscope to observe, draw and label a selection of plant and animal cells. A magnification scale must be included.
