Cell Cycle
AP Biology
Prokaryotic cell cycle: Binary Fission
What is G0? What sort of
cells enter this phase?
Note:
● difference between chromatin and chromatid
● what 2 molecules make up chromatin
● What are histones?
Note:
● prometaphase events
● role of kinetochore and
non kinetochore
microtubules.
During which stages
of the cell cycle does
a chromosome
consist of two
identical chromatids?
Identify mitotic phases.Plant or animal cell?
Identify mitotic phases.
Plant or animal cell?
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:
G1/S checkpoint
G2 checkpoint
spindle checkpoint
1. Diagram the relationship between cdk and cyclin.
2. 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
3. Describe how cancer treatments work and why they are not good for the body
Do molecules
present in the cell
regulate the cell
cycle?
Cancer
