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 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

Do molecules present in the cell regulate the cell cycle?

Cancer
