What you will learn
In this course students will learn exactly what they need to know for their biology exams. Students will learn about:
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
Understand that the nucleus of a cell contains chromosomes on which genes are located
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 cy
Understand that an RNA molecule is single stranded and contains uracil (U) instead of thymine (T)
Describe the stages of protein synthesis including transcription and translation, including the role of mRNA, ribosomes, tRNA, codons and anticodons
Understand how genes exist in alternative forms called alleles which give rise to differences in inherited characteristics
Understand the meaning of the terms: dominant, recessive, homozygous, heterozygous, phenotype, and genotype
Understand the meaning of the term codominance
Understand that most phenotypic features are the result of polygenic inheritance rather than single genes
Describe patterns of monohybrid inheritance using a genetic diagram
Understand how to interpret family pedigrees
Predict probabilities of outcomes from monohybrid crosses
Understand how the sex of a person is controlled by one pair of chromosomes, XX in a female and XY in a male
Describe the determination of the sex of offspring at fertilisation, using a genetic diagram
Understand how division of a diploid cell by mitosis produces two cells that contain identical sets of chromosomes
Understand that mitosis occurs during growth, repair, cloning and asexual reproduction
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 geneticall
Understand how random fertilisation produces genetic variation of offspring
Know that in human cells the diploid number of chromosomes is 46 and the haploid number is 23
Understand that variation within a species can be genetic, environmental, or a combination of both
Understand that mutation is a rare, random change in genetic material that can be inherited
Understand how a change in DNA can affect the phenotype by altering the sequence of amino acids in a protein
Understand how most genetic mutations have no effect on the phenotype, some have a small effect and rarely do they have a significant effect
Understand that the incidence of mutations can be increased by exposure to ionising radiation (for example, gamma rays, x-rays and ultraviolet rays) and some ch
Explain Darwin’s theory of evolution by natural selection
Understand how resistance to antibiotics can increase in bacterial populations, and appreciate how such an increase can lead to infections being difficult to co
Understand the differences between sexual and asexual reproduction
Understand that fertilisation involves the fusion of a male and female gamete to produce a zygote that undergoes cell division and develops into an embryo
Describe the structures of an insect-pollinated and a wind-pollinated flower and explain how each is adapted for pollination
Understand that the growth of the pollen tube followed by fertilisation leads to seed and fruit formation
Understand how germinating seeds utilise food reserves until the seedling can carry out photosynthesis
Understand that plants can reproduce asexually by natural methods (illustrated by runners) and by artificial methods (illustrated by cuttings)
Understand how the structure of the male and female reproductive systems are adapted for their functions
Understand the roles of oestrogen and progesterone in the menstrual cycle
Understand the roles of FSH and LH in the menstrual cycle
Describe the role of the placenta in the nutrition of the developing embryo
Understand how the developing embryo is protected by amniotic fluid
Understand the roles of oestrogen and testosterone in the development of secondary sexual characteristics
