A Level Biology Topic 7 - Modern Genetics
Edexcel Biology B
PowerPoint presentation of over 100 slides covering the whole topic
This topic builds on the knowledge of nucleic acids and proteins and how they are involved in gene expression. Knowledge of epigenetics, the use of stem cells and how these are contributing to medical advances are considered. The ethical
implications of the use of gene technology in scientific developments are discussed.
7.1 Using gene sequencing
7.2 Factors affecting gene expression
7.3 Stem cells
7.4 Gene technology
This fully editable PowerPoint presentation covers the entire of Topic 8 from the Edexcel Biology B A Level course.
How are mutations the source of new variations and how do the processes of random assortment and crossing over during meiosis give rise to new combinations of alleles in gametes?
How does random fertilisation during sexual reproduction bring about genetic variation?
Understand the terms ‘genotype and phenotype’,’ homozygote and
heterozygote’, ‘dominance’, ‘recessive’, ‘codominance’ and ‘multiple alleles’.
Be able to construct genetic crosses and pedigree diagrams.
Can you explain sex linkage on the X chromosome, including haemophilia in
Humans?
Can you explain the inheritance of two non-interacting unlinked genes?
Do you understand that autosomal linkage results from the presence of alleles on the same chromosome and that the results of crosses can be explained by the events of meiosis, including black/grey body and long/vestigial wing in Drosophila?
Can you use the chi squared test to test the significance of the difference between observed and expected results?
Understand that selection pressures acting on the gene pool change allele frequencies in the population, including:
●Stabilising selection maintaining continuity in a population
●Disruptive selection leading to changes or speciation.
Understand that sometimes changes in allele frequencies can be the result of chance and not selection, including genetic drift.
Understand that allele frequencies can be influenced by:
● population bottlenecks
● founder effect.
Understand how the Hardy-Weinberg equation can be used to monitor changes in the allele frequencies in a population.
PowerPoint for topic 7.2 Factors affecting gene expression of A Level Biology Edexcel B
i Know that transcription factors are proteins that bind to DNA.
ii Understand the role of transcription factors in regulating gene expression.
iii Understand how post–transcription modification of mRNA in eukaryotic cells
(RNA splicing) can result in different products from a single gene.
iv Understand that gene expression can be changed by epigenetic modification,
including non-coding RNA, histone modification and DNA methylation.
v Know that epigenetic modification is important in ensuring cell differentiation.
