  1. Mitosis and Heredity Review

  2. 1. As you become an adult, the cells in you body • keep dividing • stop dividing • grow bigger • can’t repair themselves A

  3. 2. How do cells share genetic material? • Their chromatids join. • They go through telophase. • They divide. • They become specialized. C

  4. 3. The cell cycle begins with • cytokinesis • interphase • mitosis • metaphase B

  5. 4. The cell cycle ends with • cytokenesis • Interphase • metaphase • prophase A

  6. 5. How does a cell prepare for mitosis? • It goes through cytoKinesis. • It forms new chromosomes. • It rests during interphase. • It makes exact copies of its DNA. D

  7. 6. A cell grows and carries out life functions in • telephase • prophase • anaphase • interphase D

  8. 7. What process completes division in a plant cell? • A cell plate grows between the two new nuclei. • A fiber ring forms in the center of the dividing cell. • The cell membrane is pinched inward. • Chromosomes line up in the middle of the cell. A

  9. 8. Bread yeast reproduce by developing tiny extensions on their bodies. This is an example of • budding • binary fission • regeneration • sexual reproduction A

  10. 9. The offspring produce by asexual reproduction • are genetically identical to their parents • are genetically different from their parents • have half as much DNA as their parents • get half of their DNA from each parent A

  11. 10. Many offspring can be produced very quickly • during a single cell cycle • through the formation of chromosomes • when two parent cells produce one offspring • through asexual reproduction D

  12. 11. Which of the following is true of all cells? • All cells have DNA in their nucleus • All cells come from existing cells. • All cells are specialized. • All cells reproduce by budding B

  13. 12. A cell produces two genetically identical daughter cells when it • condenses DNA • make proteins • undergoes mitosis • enters interphase C

  14. 13. Most multicellular organisms grow and develop because their cells • grow smaller with age • become specialized at birth • divide during interphase • continue to divide D

  15. 14. Which of the following correctly sequences the steps in the cell cycle? • cytokinesis, mitosis, interphase • telophase, anaphase, metaphase, prophase • interphase, mitosis, cytokinesis • prophase, anaphase, metaphase, telophase C

  16. 15. Cells prepare for cell division during • interphase by duplicating their DNA • mitosis by dividing their DNA • Anaphase by condensing their DNA • telophase by splitting their DNA A

  17. 16. What happens during mitosis • chromosomes line up in the center of the cell. • Cytokinesis takes place. • A cell completes one entire cell cycle. • The cell nucleus makes two copies of DNA A

  18. 17. After mitosis, the number of chromosomes in a daughter cell is • half the number in the parent cell • one-quater the number in the parent cell • twice the number in the parent cell • the same as the number in the parent cell D

  19. 18. Asexual reproduction in most organisms involves • mitosis by two parents • mitosis by one parent • binary fission by both parents • regeneration by one parent B

  20. 19. Your genes are inherited from your • parents • allelles • gametes • offspring A

  21. 20. Various forms of the same gene are called • chromosomes • alleles • homologs • genotypes B

  22. 21. An animal has an allele for white fur, but its fur is black. The allele for white fur is • dominant • incomplete • not hereditary • recessive D

  23. 22. Your eye color is a(n) • allele • homolog • phenotype • genotype C

  24. 23. The way in which parents’ alleles might combine in their offspring can be shown in a • phenotype • genotype • coin toss • Punnett square D

  25. 24. In a plant, tall (D) is the dominant allele. Short (d) is the recessive allele. Which genotype would a short offspring have? • dD • dd • Dd • DD B

  26. 25. DNA is always copied before the process of cell division called • mitosis • meiosis • sexual reproduction • fertilization A

  27. 26. Each box in a Punnett square shows • One possible allele from one parent • one possible allele from each parent • two possible alleles from one parent • two possible alleles from each parent B

  28. Answers by question # - not slide # • 1. A, 2. C, 3. B., 4. A, 5. D, 6. D, 7. A, 8. A, 9. A, 10. D, 11. B, 12. C, 13. D, 14. C, 15. A, 16. a, 17. d, 18. b, 19. a, 20. b, 21. d, 22. c, 23. d, 24. b, 25. a, 26. b.
