AQA AS-level BiologyTopic 5 of 1412 lessons

Revision notes for The Cell Cycle in AQA Biology (7401). Every lesson in BrainCake comes with R.E.C.I.P.E. recall steps, a quick check and spaced reviews.

  1. The Cell CycleCells undergo a regular cycle of growth and division.
  2. MitosisMitosis is important in growth, repair and asexual reproduction.
  3. ProphaseProphase: The nuclear envelope breaks down and the nucleolus disappears.
  4. MetaphaseMetaphase: By metaphase, chromosomes have reached the metaphase plate (or equator) in the middle of the cell.
  5. AnaphaseAnaphase is the stage of mitosis that follows metaphase.
  6. TelophaseTelophase is the final stage of mitosis.
  7. CytokinesisCytokinesis is the cell division that takes place after mitosis.
  8. The Importance of MitosisMitosis is used for growth, repair and asexual reproduction.
  9. Cancer and the Control of MitosisThere are about 200 types of cancer characterised by uncontrolled cell division.
  10. Treatment of CancerCancer is treated by killing the abnormal cells.
  11. Cell Division in Prokaryotic CellsIn prokaryotes the circular DNA attaches to the cell membrane and replicates.
  12. The Replication of VirusesViruses can only replicate by using the host cell apparatus as they are non-living.
