CHAPTER 12 THE CELL CYCLE Learning objectives The Key Roles of Cell Division 1 Explain how cell division functions in reproduction growth and 2 Describe the structural organization of a prokaryotic and repair eukaryotic genome 3 Describe the major events of eukaryotic cell division that enable the genome of one cell to be passed on to two daughter cells 4 Describe how the 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 7 Recognize the phases of mitosis from diagrams and of each phase micrographs 8 Draw or describe the mitotic spindle including centrosomes kinetochore microtubules nonkinetochore microtubules asters and centrioles in animal cells 9 Describe the changes in the mitotic spindle during each phase of mitosis 10 Describe two mechanisms that explain how motor proteins associated with the kinetochore microtubules bring about the poleward movement of chromosomes Explain how nonkinetochore microtubules lengthen the cell during anaphase Compare cytokinesis in animals and plants Describe the process of binary fission in bacteria Regulation of the Cell Cycle Describe the roles of checkpoints cyclin Cdks and MPF in the cell cycle control system the cell cycle control system Describe the internal and external factors that influence Explain how the abnormal cell division of cancerous cells escapes normal cell cycle controls Distinguish between benign malignant and metastatic tumors 11 12 13 14 15 16 17 Learning Objectives for Campbell Reece Biology 8th Edition Pearson Education Inc 1 of 2 Learning Objectives for Campbell Reece Biology 8th Edition Pearson Education Inc 2 of 2
