AP Biology

2. Prokaryotic cell cycle: Binary Fission

3. What is G0? What sort of cells enter this phase?

4. Note:
difference between chromatin and chromatid
what 2 molecules make up chromatin
What are histones?

7. Note:
prometaphase events
role of kinetochore and non kinetochore microtubules.

9. Identify mitotic phases.Plant or animal cell?

10. Identify mitotic phases.
Plant or animal cell?

11. Questions To Answer
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?
What does it mean when we say that there are several “checkpoints” that occur during the cell cycle?
What are the “Questions” that a cell must “answer” during each of the following checkpoints:
G1/S checkpoint
G2 checkpoint
spindle checkpoint
Diagram the relationship between cdk and cyclin.
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
Describe how cancer treatments work and why they are not good for the body
