Edexcel A-Level Biology Topic 3 REVISION (Voice of the Genome)

This is a fully-resourced revision lesson that uses a combination of exam questions, understanding checks, quick differentiated tasks and quiz competitions to enable students to assess their understanding of the content found within Topic 3 (Voice of the Genome) of the Pearson Edexcel A-level Biology A specification.

The sub-topics and specification points that are tested within the lesson include:

  • Know the ultrastructure of eukaryotic cells
  • Understand the role of the rER and the Golgi apparatus in protein transport within cells
  • Know the ultrastructure of prokaryotic cells
  • Be able to recognise the organelles of eukaryotic cells from EM images
  • Know that a locus is the location of a gene on a chromosome
  • Understand the linkage of genes on a chromosome and sex linkage
  • Understand the role of meiosis in ensuring genetic variation
  • Understand the role of mitosis and the cell cycle in producing identical daughter cells
  • Understand how gene expression is controlled
  • Understand how phenotype is the result of an interaction between genotype and the environment
  • Know how some phenotypes are affected by multiple alleles as well as the environment and how this shows continuous variation

Students will be engaged through the numerous quiz rounds such as “Is your knowledge of the Lac Operon LACKING” and “Can I have a P please Bob” whilst crucially being able to recognise those areas which require their further attention during general revision or during the lead up to the actual A-level terminal exams
