Prior to cell division, the DNA and proteins associated with the DNA coil into structures called chromosomes. 19. A frog somatic cell is diploid and therefore has twice the number of chromosomes of the haploid frog egg cell. 20. When one or more chromosomes fail to separate properly during cell division in gamete production, one new cell will receive both chromosomes, and the other new cell will receive none. As a result, one gamete will be produced that has one extra chromosome, and another gamete will be produced that is missing one chromosome. 21. If conditions are favorable for cell division during the first growth phase, certain proteins will stimulate the cell to begin the synthesis phase, during which DNA is duplicated. During the second growth phase, the DNA replication is checked by DNA repair enzymes. If everything is in order, proteins then initiate the beginning of mitosis. At the final checkpoint, the cell is prompted to exit from the mitosis phase and to begin the first growth phase again. 22. prophase, metaphase, anaphase and telophase 23. During prophase, chromosomes coil up and become visible, the nuclear envelope dissolves, and the spindle apparatus forms. During metaphase, the chromosomes line up in the center of the cell. During anaphase, the centromeres divided and the chromatids are drawn to opposite poles by spindle fibers. During telophase, a nuclear envelope forms around the chromosomes at each pole. The chromosomes uncoil, and the spindle dissolves. 24. The phases of interphase are the first growth (G 1 ) phase, the synthesis (S) phase, and the second growth (G 2 ) phase. The G 1 phase is the growth phase of a cell when the cell grows rapidly and carries out its routine functions. DNA is copied during the S phase. In the G 1 phase, preparations are made for nuclear division. Proteins needed for cell division are synthesized. 25. growth, development, repair, reproduction Quiz SECTION: CHROMOSOMES 1. d 6. c 2. b 7. b 3. e 8. c 4. c 9. b 5. a 10. d SECTION: THE CELL CYCLE 1. d 6. b 2. e 7. a 3. b 8. c 4. a 9. b 5. c 10. b SECTION: MITOSIS AND CYTOKINESIS 1. e 6. c 2. a 7. b 3. d 8. d 4. c 9. a 5. b 10. d Chapter Test (General) 1. f 11. d 2. e 12. b 3. h 13. c 4. i 14. c 5. a 15. b 6. c 16. d 7. d 17. a 8. g 18. d 9. j 19. a 10. b 20. d Holt Biology 84 Chromosomes and Cell Reproduction
