Cell Cycle, Mitosis and Meiosis

Questions to answer:

  1. Why does a multicellular organism need to control and coordinate cell division?  What might be the consequences of uncontrolled cell division in a multicellular organism?
  2. What does it mean when we say that there are several “checkpoints” that occur during the cell cycle?
  3. What are the “Questions” that a cell must “answer” during each of the following checkpoints:
  1. G1/S checkpoint
  2. G2 checkpoint
  3. spindle checkpoint
  1. Diagram the relationship between cdK, and cyclin.
  2. Give an example of an external signal that regulates cell division and explain how it works.
  3. Compare and contrast the functions of proto-oncogenes and tumor suppressor genes.  Give an example of each and explain why mutations in these genes can lead to cancer.
