Chromosomes and Cell Cycle Test Review Chromosome Questions 1. Put the following in order from smallest to largest: Cell, Chromosome, Nucleus, DNA, human 2. What is a centromere? 3. How many pairs of chromosomes do humans have? 4. What’s the difference between Chromatid and Chromatin? 5. Draw a Chromosome and Label a chromatid and centromere: Mitosis-Cell Division 6. Name the Steps of the entire cell cycle in order – Including all 3 stages of interphase, all 4 stages of mitosis, cytokensis. 7. What is a cell doing during interphase? (be sure to name the one thing that only happens during interphase) 8. Interphase has 3 stages Describe all 3. G1SG2 9. Draw interphase. 10. What happens during prophase? 11. Draw prophase. 12. What happens during metaphase? 13. Draw metaphase. 14. What happens during anaphase? 15. Draw anaphase. 16. What happens during telophase? 17. Draw telophase. 1 18. What happens during cytokensis? 19. Draw cytokensis. 20. What do the centrioles do during mitosis? 21. If an animal has 40 chromosomes in each of its somatic cells and divides in mitosis how many chromosomes will the new (daughter) cells have? 22. How is the cell cycle different in a plant than in an animal? (think about cytokensis) 23. What is purpose of mitosis? - Name 3 things that Mitosis controls in your body. 24. A mutated cell that is undergoing constant, uncontrolled cell growth is considered this25. Mitosis produces how many new cells? 26. If a cell has 40 chromosomes, how many chromosomes will each new cell have after MITOSIS? 27. What is a somatic cell? 28. 90% of a cell life span is spent in one stage? 29. After a cell completes Cytokenisis, What happens next? 30. If we compared the original cell to the 2 new daughter cells at the end of mitosis. What observations could be made? 31. The nuclear envelope disappears in what stage? 32. Label the following stages and number them in the order they take place from 1-6. _________________ ________________ _________________ ------------------------- 2 ____________ _______________
