BIO II: Mitosis/Meiosis Test Review Sheet
1. At what stage of MITOSIS does:
 DNA replication occur?
 The Centrioles begin to move apart in animal cells?
 The centromeres uncouple, sister chromatids are separated and each new
chromosome moves to the opposite pole of the cell?
2. The formation of a cell plate is beginning to form across the middle of the cell
and 2 distinct nuclei are visible at opposite ends of the cell? What kind of cell
is this and what stage of cell division is it likely in?
3. What happens during the S phase of the cell cycle?
4. A cell that has 24 chromosomes at the start of mitosis would have how many
at the completion of mitosis?
5. List, in order, the correct sequence of events for the cell cycle and mitosis.
6. In a typical cell, cytokinesis generally overlaps which stage?
7. During which phases of mitosis are sister chromatids found?
8. How is the diploid number of chromosomes restored after MEIOSIS?
9. What is a karyotype?
10. What is a somatic cell? How many chromosomes are found in the somatic
cells of humans?
11. During which stages of MEIOSIS do the following events occur? Be sure to
designate whether it is Meiosis I or Meiosis II.
 Tetrads of chromosomes line up at the metaphase plate:
 Synapsis of homologous pairs occurs:
 Crossing over may occur:
 Centromeres of sister chromatids uncouple and sister chromatids
separate:
12. Use the following drawing to answer the following questions:


Which diagram represents Prophase I of Meiosis?
Which diagram represents Anaphase I of Meiosis?
13. What is a centromere?
14. What is the end result of Meiosis?
15. How is Meiosis different from Mitosis? How is Meiosis II similar to mitosis?
16 What are some events that you would expect to occur in Meiosis but not in
Mitosis?
17. What is Binary Fission? What kind of cells undergo Binary Fission?
18. A human cell that contains 22 autosomes and one X chromosome is a :
