1. Which of the cell stages is not actually a part of mitosis? (HINT: It’s the “normal”, not dividing stage...)
a. Interphase
c. Metaphase
e. Telophase
b. Prophase
d. Anaphase
2. When is the DNA copied? (When does a monovalent chromosome become a bivalent chromosome?)
a. Interphase.
c. Metaphase.
e. Telophase
b. Prophase.
d. Anaphase
3. Imagine you are observing a cell that has 8 bivalent chromosomes lined up SINGLE FILE in the middle.

meiosis...)

cell. What stage is the cell in?
a. Metaphase of mitosis
c. Metaphase II of meiosis
b. Metaphase I of meiosis
5. If you looked at the chromsomes of a pollen grain that came from a 22-chromosome plant, how many
