The Cell Cycle and Meiosis Test Study Guide 2007
1. List each part of the cell cycle and give a brief description of the main events that
occur.
2. What stage of the cell cycle do cells spend most of their time in?
3. Why do cell divide?
4. Give examples of humans cells that divide often. Give examples of human cells that
rarely divide.
5. Draw a chromosome. Label the centromere, sister chromatids, and chromatin.
6. Draw a histone and a nucleosome? What are these things and how do they relate to
chromosome structure?
7. What is the difference between malignant and benign tumors?
8. What is cancer?
9. What is metastasis?
10. Write a paragraph describing the following terms: gametes, zygote, sperm, egg,
haploid, diploid, fertilization, 46, 23, and sexual reproduction.
11. Make a chart comparing meiosis from mitosis (there should be at least 4 differences
noted)
12. What is a karyotype? How can karyotypes help diagnose genetic disorders?
13. What are homologous pairs? How many homologous pairs does a female
dog (n=39) have in her regular body cells?
14. Why do stem cells hold so many possibilities for medical uses?
15. What are two sources of stem cells?
16. What are tetrads?
17. Explain two events that occur during meiosis that contribute to genetic diversity?
18 Why is genetic diversity amongst members of a species important?
19. We discussed two chromosomal disorders in class. Briefly explain what they are,
some of their effects, and the specific chromosomal abnormalities that cause them.
20. What is a monosomy? What is a trisomy?
