How Do Cells Divide?
1. Regarding the mitotic phase of the cell cycle:
How does its length compare to the S phase of the cycle?
What are the two major events that occur during the mitotic phase?
What "choices" does a cell have at the end of the mitotic phase?
How does the nature of chromatin change at the end of the mitotic phase (extent
of packing)?
2. Indicate the location and function of the following structures during mitosis:
Location
Function
Centromere
Kinetochore
Centrosome
Spindle (and
microtubules)
3. Be able to recognize interphase and the following stages of mitosis in both animal
and plant cells: prophase, metaphase, anaphase, telophase.
Draw the chromosomes/chromatids within a cell at each of the above stages of
mitosis; label chromosomes (or chromatids) and the nuclear membrane (if
present).
Prophase
Metaphase
Anaphase
Telophase
4. Explain what occurs during anaphase of mitosis and the role of motor proteins in this
process.
5. Compare the process of cytokinesis in animal vs. plant cells.
