  • BQ02 Biology: How do living things grow and reproduce?

Description

This unit covers the structure and function of eukaryotic and prokaryotic cells, DNA as the genetic material, and key genetic terms. It also explains protein synthesis, genetic variants, and how DNA structure affects proteins. The emphasis is on using models to explain scientific concepts.

This unit builds on pupils’ prior learning from Reproduction in plants, where they explored how genetic information is passed from one generation to the next through reproductive processes. It deepens their understanding by examining the structure and function of DNA and the genome, focusing on how genetic information is stored and expressed. This prepares pupils for the next unit, Inheritance, genotype and phenotype, where they will apply their knowledge to explore how genetic variations influence traits, reinforcing the principles of heredity and genetic inheritance.

  1. The genome
  2. The chemical structure of DNA
  3. The genome, the environment and phenotype
  4. The genetic code
  5. Protein synthesis
  6. Mutations and genetic variants
  7. Genetic variants in genes can influence phenotype
  8. Genetic variants in non-coding DNA can influence phenotype

  • All organisms are made up of one or more cells.
  • Genetic material stored in cells provides instructions for growth and other life processes.
  • The genetic material of all organisms is made of a chemical substance called DNA.
