                       Reading Guide – Mitosis and Cytokinesis


1. Describe each of the 4 stages of mitosis. Describe interphase in detail.

2. Draw each stage of mitosis and label every part of your pictures.

3. In the cell cycle, what happens after mitosis?

4. What role do spindle fibers play in mitosis?

5. What would happen if a cell was somehow missing spindle fibers?

6. What part of the chromosome do the spindle fibers connect to during mitosis?

7. Suppose that all of the enzymes that control the normal cell cycle were identified.
Suggest some ways that this information might be used to fight against cancer.

8. Someone with Cancer, has cells that divide quickly and constantly. If you were asked
to develop a drug that stopped Cancer, what would your drug do to stop mitosis from
working without harming the genetic information? What would you name your drug?
                     Drug Name _____________________________

9. Suppose during the process of mitosis, some of spindle fibers attached improperly and
accidentally pulled both chromatids of a chromosome to one side of the cell. How might
this be problematic for the cell?

10. When you cut yourself, how might the cell cycle play an important role in healing
the cut?
