Presentation Transcript

  1. Biology 1060Chapter 12 The Cell Cycle

  2. Cell Division • Describe the role of cell division in both unicellular and multicellular organisms • Define and describe the cell cycle • Explain why control of cell division is important

  3. Genetically Identical Offspring • Describe the processes important in cell division • Differentiate between DNA, chromosome, and chromatin, between somatic cells and gametes and their genomes

  4. Chromosome Distribution • Describe the duplicated chromosome and its constituents • Discuss the two processes that result in individual offspring cells • Compare and contrast mitosis and meiosis • Evolution Connection p. 235

  5. Cell Cycle • Define cell cycle • Describe the events of each part of the cell cycle • Explain their significance to cell reproduction • Define mitosis and discuss its stages

  6. Mitotic Spindle • Discuss the interactions of microtubules during the cell cycle • Describe the centrosome and the importance of its components in formation of the spindle • Describe components of the spindle and their association with cell components

  7. Kinetochores • Discuss the interactions of components of the spindle with other cellular components • Describe the roles of the kinetochore, polar and aster microtubules • Discuss how kinetochore microtubules move chromosomes during the mitotic process • Scientific Inquiry p. 235

  8. Cytokinesis • Describe cytokinesis in animal cells • Describe cytokinesis in plant cells • Discuss why each is different from the other

  9. Binary Fission • Describe binary fission and the organisms using it • Differentiate binary fission from mitosis • Discuss how chromosome movements differ in each cell division model

  10. Evolution of Mitosis • Describe the origin of mitosis and cite evidence to support the hypothesis • Discuss the significance of particulars of dinoflagellate and diatom cell division to this hypothesis

  11. Cell Cycle Regulation • Discuss why control of the cell cycle is of interest • Describe the evidence for current ideas of cell division control • Discuss where in the cell cycle checkpoints exist • discuss the effect of “go” or “no go” signals with examples

  12. Cell Cycle Clock • Name and describe the interactions of two cell cycle regulatory molecules • Describe the activation caused by MPF • Describe the changes occurring as MPF’s cyclin is destroyed

  13. Stop and Go • Describe how unattached kintochores prevent completion of mitotic division • Discuss the control by PDGF in culture and in the organism • Discuss the effects of density and anchorage sites on cell division

  14. Cancer • Differentiate normal from cancer cells and the mechanisms by which their cell cycles are controlled • Describe transformation • differentiate between benign and malignant tumors • Discuss treatments for cancer and their effects on normal cells • Science, Technology, and Society p. 235
