| March 13, 2016

1. A sperm cell is an example of:

· a zygote

· a gamete

· a germ cell

· a somatic cell

2. During which stage of the cell cycle is the DNA replicated?

· Mitosis

· S

· G2

· Cytokinesis

3. Somatic cells are reproduced during the process of _____________:

· mitosis

· fusion

· meiosis

· fission

4. DNA that is tightly wound around histone proteins is the easiest to divide. Is this statement true or false?

· True

· False

5. All of the following pairings between a cell cycle phase and what happens during it are correct, except

· S- the cell is dividing

· G0- the cell is mature and does not cycle anymore.

· M- the cell is undergoing mitosis

· G2- the cell is preparing to divide

· G1- the cell is growing and increasing its mass

6. If a germ cell has 20 chromosomes, how many chromosomes will you find in the daughter cells, after meiosis?

· 20

· 10

· 30

· 40

7. The products of MITOSIS are:

· Four genetically identical cells

· Two genetically identical cells

· Two genetically unique cells

·

· Four genetically unique cells

8. During what stage of the cell cycle does the cell grow and carry out it regular functions?

· Mitosis

· S

· G1

· G2

9. If a somatic cell has 24 chromosomes, how many chromosomes will you find in the daughter cells, after mitosis?

· 36

· 24

· 48

· 12

10. During the S phase of the cell cycle, DNA is replicated. What form would you expect the DNA to be in?

· It would be in a loose pile.

· It would be made of separate nucleotides just floating in the nucleus.

· It would be tightly wound around histone proteins as chromosomes.
