Revise: Cells and their uses
- Revise: Cell division and its role in growth and repair
  Animal, plant, fungal and bacterial cells divide to allow an increase in number and the repair of damaged cells in multicellular organisms.
- Revise: Controversial biological procedures
  Modern biotechnology techniques such as gene therapy and genetic engineering have potentially beneficial outcomes in healthcare and food manufacture but it is argued that there are risks involved.
- Revise: DNA, genes and chromosomes
  DNA carries the genetic information in the cells of all living organisms. Genes contain codes for the assembly of amino acids into all the proteins required in the body.
- Revise: Therapeutic use of cells
  Genetic engineering is the transfer of DNA between organisms. Bacteria receiving human DNA can produce proteins such as insulin. Stem cells can potentially develop into specialised body parts.
