Questions:
1. What is mitosis?
2. In order, what are the four main stages of mitosis?
3. What is the name of the stage a goes through just prior to mitosis?
4. What is the main event of interphase?
5. What are two important events of prophase?
6. What is the main event of metaphase?
7. What structure is involved in moving chromosomes during mitosis?
8. What is the main event of anaphase?
9. What are two important events of telophase?
10. At the completion of mitosis when the cell divides, what name is given to the two new cells?
11. You began life as a one-called structure called zygote. What process then took place over and over to build a body containing billions of cells?

Answers:
a. Interphase
b. The chromosomes in the nucleus of the cell make identical copies of themselves.
c. The chromosomes move toward and line up along the center of the cell, called the equator.
d. The nuclear membrane disappears and the chromosomes become distinct.
e. Mitosis
f. New nuclear membranes form around each of the two sets of chromosomes, and the cell divides into two daughter cells.
g. Prophase, metaphase, anaphase, and telophase.
h. Daughter cells
i. Microtubules
j. Division of the nucleus of the cell (usually followed by division of the cell itself)
k. The microtubules pull one set of chromosomes to one side of the cell and an identical set to the opposite side of the cell.

I agree with the other person. If you study this, even a dummy could figure it out. Please try to ask for more difficult specific help next time.
