Mitosis Questions Key

On a separate sheet of paper answer these questions in complete sentences.

  1. Compare and contrast how a prokaryotic and eukaryotic cell replicate their genome.

    Eukaryotic cells under go mitosis while prokaryotic cells do binary fission.

  2. How are chromatin and a chromosome related?

    Chromosomes are made of chromatin.

  3. Describe (not just list) the five stages of the cell cycle.
    • G1 - growth phase
    • S - genome replicated
    • G2 - prep for mitosis
    • mitosis - divide chromosomes
    • cytokinesis - cell splits
  4. Imagine you are looking at a microscope slide of eukaryotic cell tissue. The field of view shows approx. 100 cells. Estimate the numbers of cells that are in each stage of the cell cycle.
    • G1 = 40
    • S = 45
    • G2 = 10
    • mitosis = 5
    • cytokinesis = "0"
  5. List the four stages of mitosis. PMAT
  6. Describe a distinct characteristic of each stage of mitosis.
    • Prophase - Chromosomes condense and nuclear membrane fragments.
    • Metaphase - Chromosomes align along metaphase plate.
    • Anaphase - Chromosomes divide.
    • Telophase - Chromosomes uncoil and nuclear membrane reappears.
