1 Chapter 12 Objectives: Objectives: 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. 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. Draw or describe the spindle apparatus, including centrosomes, kinetochore microtubules, nonkinetochore microtubules, asters, and centrioles (in animal cells). 9. Describe what characteristic changes occur in the spindle apparatus during each phase of mitosis. 10. Explain the current models for poleward chromosomal movement and elongation of the cell’s polar axis. 11. Compare cytokinesis in animals and in plants. 12. Describe the process of binary fission in bacteria and explain how eukaryotic mitosis may have evolved from binary fission. 13. Describe the roles of checkpoints, cyclin, Cdk, and MPF in the cell cycle control system. 14. Describe the internal and external factors that influence the cell cycle control system. 15. Explain how the abnormal cell division of cancerous cells escapes normal cell cycle controls. 16. Distinguish among benign, malignant, and metastatic tumors. Key Terms: anaphase anchorage dependence aster benign tumor binary fission cell cycle cell cycle control system cell division cell plate centromere centrosome checkpoint chromatin chromosome cleavage cleavage furrow cyclin cyclin-dependent kinase (Cdk) cytokinesis density-dependent inhibition G0 phase G1 phase G2 phase gamete genome growth factor interphase kinetochore M phase malignant tumor meiosis metaphase metaphase plate metastasis mitosis mitotic (M) phase mitotic spindle MPF origin of replication prometaphase prophase S phase sister chromatids somatic cell telophase transformation Chapter 13 Objectives: 1. Explain in general terms how traits are transmitted from parents to offspring. 2. Distinguish between asexual and sexual reproduction. 3. Distinguish between the following pairs of terms: a. somatic cell and gamete b. autosome and sex chromosome 4. Explain how haploid and diploid cells differ from each other. State which cells in the human body are diploid and which are haploid. 5.
