Designed for the new specification IGCSE edexcel course but can be used for other examination boards. 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

Designed for the new specification AQA GCSE course but can be modified for other exam boards. 21 slides covering Homeostasis By the end of the powerpoint students would have covered: 4.5.1 Homeostasis Students should be able to explain that homeostasis is the regulation of the internal conditions of a cell or organism to maintain optimum conditions for function in response to internal and external changes. Homeostasis maintains optimal conditions for enzyme action and all cell functions. In the human body, these include control of: • blood glucose concentration • body temperature • water levels. These automatic control systems may involve nervous responses or chemical responses. All control systems include: • cells called receptors, which detect stimuli (changes in the environment) • coordination centres (such as the brain, spinal cord and pancreas) that receive and process information from receptors • effectors, muscles or glands, which bring about responses which restore optimum levels.

Designed for the new specification AQA GCSE course but can be modified for other exam boards. 25 slides covering the human endocrine system. 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
