Directions: Answer the following questions. You do not have to write in complete sentences but be clear in
your answer.
Section 1 – Chromosomes
1. Name the structure “A” in the diagram.
2. Name the structure “B” in the diagram.
3. The diagram is showing an “X” shaped chromosome. When during the
cell cycle will you see an “X” shaped chromosome?
A.
4. In order to fit in the cell DNA must become more compact. How does
happen?
5. Fill in the chart below:
Eukaryotes
Prokaryotes
Give an
example:
Shape of
chromosome:
Where is
chromosome
located within
the cell?
Method of cell
division:
B.
6. Fill in the following chart:
Diploid
Haploid
Somatic cells or
Gametes?
Number of
chromosome
sets:
Made by which
cell division
process?
Symbol?

process?

8. Label the pie chart on the right with the following words:
a. Anaphase
b. G2
c. Prophase
d. S phase
e. Cytokenesis
f. Metaphase
g. G1
h. Telophase
9. What are the three main stages of the
cell cycle?
10. Which stage of the cell cycle occupies
most of the cell’s life?
11. During what phase is the DNA copied?
12. A disruption in this process results in what disease?
13. Briefly describe what happens in each phase of mitosis:
a. Prophase:
b. Metaphase:
c. Anaphase:
d. Telophase:
14. What is the role of the mitotic spindle during mitosis?
15. Write the number that illustrates each phase of mitosis:
a. Prophase:
b. Metaphase:
c. Anaphase:
d. Telophase:
16. How does cytokinesis differ between plant and animals cells?

Section 3 - Meiosis
17. Fill in the following table:
Mitosis
Meiosis
How many
daughter cells
are produced?
Are the
daughter cells
somatic cells or
gamete?
How many sets
of
chromosomes
do the daughter
cells contain?
Are the
daughter cells
diploid or
haploid?
How many
cellular/nuclear
divisions occur?
Are the
daughter cells
identical or
genetically
different from
original cell?
18. How does crossing-over during Prophase I lead to genetic variation?
19. Why does Meiosis go through 2 different cellular divisions?
20. Why does the DNA not replicate before the second meiotic division?
21. Why does sexual reproduction require the production of gametes that contain only half the
organisms DNA?
22. What is a possible genetic disorder if Meiosis goes wrong?
