Objectives:
1. Explain hoe cell division functions in reproduction, growth, and repair.
2. Describe the structural organization of the genome.
3. Explain the difference between a chromatid and a chromosome.
4. Describe the major events of cell division that enable the genome of one cell to be passed on to two daughter
cells.
5. Describe the events in each of the following phases of the cell cycle; G1, S, G2, and M.
6. List the phases of mitosis and describe the events characteristic of each phase.
7. Recognize the phases of mitosis from diagrams and micrographs.
8. Compare cytokinesis in animals and plants.
9. Describe the process of binary fission in bacteria and how this process may have evolved in eukaryotic mitosis.
10. Describe the role of checkpoints, cyclin, Cdk, and MPF in the cell cycle control system.
11. Describe the internal and external factors that influence the cell cycle control system.
12. Explain how the abnormal cell division of cancerous cells differs from normal cell division.
