C h a p t e r 1 2 The Cell Cycle Teaching Objectives The Key Roles of Cell Division 1. Explain how cell division functions in reproduction, growth, and repair. 2. Describe the structural organization of a prokaryotic and a eukaryotic genome. 3. Describe the major events of cell division that enable the genome of one cell to be passed on to two daughter cells. 4. Describe how chromosome number changes throughout the human life cycle. The Mitotic Cell Cycle 5. List the phases of the cell cycle and describe the sequence of events that occurs during each phase. 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.
