Cell Cycle Assignment
1. Explain the difference between a prokaryotic and eukaryotic cell
2. How do somatic and germ cells differ in their number of chromosomes (in humans). What process does each use to divide?
3. What is happening during G1, S, G2, and M stages of the cell cycle?
4. Explain each stage of mitosis. Be sure to use key terms
5. How is mitosis different than cytokinesis?
6. Explain the differences in how animal and plant cells finish dividing
7. What is the purpose of cell checkpoints? Where are they and what is each looking for? What are 2 major issues that would
lead to cells being destroyed?
8. When would a cell enter the G0 phase?
9. What components make up the spindle apparatus? What do they do? How are the microtubules shortened during anaphase?
10. Explain how enzymes are involved in catalyzing and regulating the cell cycle. Use specific examples
11. How are cancer cells linked to cyclin?
12. What is meant by metastasis?
13. Explain how the mutation of 2 genes can lead to cancer
14. How is asexual reproduction different from sexual reproduction?
15. What is the different between genotype, karyotype and phenotype?
16. Explain the difference between autosomes and sex chromosomes in terms of numbers and function
17. What is meant by ploidy, haploid, diploid?
18. Explain the steps that occur during meiosis. Drawing out the stages help to show your understanding
19. Explain the differences between Meiosis I and Mitosis
20. Explain all the ways that genetic variation occur during cell division
Describing chromosomes:
21. In figure 13.4, how many DNA molecules (double helices) are present? What is the haploid number
of this cell? Is a set of chromosome haploid or diploid?
22. In the karyotype above, how many pairs of chromosomes? How many sets?
23. A certain eukaryote lives life as a unicellular organism, but during environmental stress it forms
gametes. The gametes fuse, and the resulting zygote undergoes meiosis, generating new single cell.
What type of organism could this be? Explain
