We discussed what is going to be on tomorrow's test:
- All of Chapter 7 - membrane structure, transport (including water potential)
- Cell communication from blog on 10/
- Ch. 12.1 and 12.2 - cell cycle and mitosis, including cytokinesis adn binary fission
- Cancer as a disruption of cell cycle controls - roles of protooncogenes and tumor suppressor genes
- What is the normal role of a proto-oncogene?
- What is the normal role of a tumor suppressor gene?
- Why must there be mutations to both tumor suppressor genes and proto-oncogenes for cancer to occur?
- Would you need mutations in both copies of your proto-oncogenes to cause a problem to the cell cycle? Explain.
- Would you need mutations in both copies of your tumor suppressor genes to cause a problem to the cell cycle? Explain.
