3.

What is cytokinesis?

a)

When 2 cells merge together to make 1 giant cell

b)

The end of the cell cycle when the cell divides and mitosis is complete

c)

The stage when DNA condenses into chromosomes

d)

The stage where chromosomes are pulled to opposite ends of the cell.

4.

How many chromosomes does a human somatic (body) cell have?

a)

46

b)

23

c)

42

d)

26

5.

How many chromosomes does a human egg or sperm (gamete) cell have?

a)

23

b)

46

c)

42

26

6.

Daughter cells created by meiosis II have

a)

half the parents DNA

b)

exact copy of the parent's DNA

c)

twice the parent's DNA

d)

created their own DNA from scratch

7.

What is "crossing over"?

a)

The exchange of genes between chromosomes during meiosis that results in genetic diversity.

b)

Programmed cell death (cell suicide) to prevent the spread of mutated/cancerous cells.

c)

A type of cell division that creates gametes (sperm and egg cells).

d)

A type of cell division that results in two daughter cells each having the same number of chromosomes as the parent cell.

8.

What is a difference between mitosis and meiosis? Mark ALL that apply!

a)

Mitosis occurs in the cytoplasm and Meiosis occurs in the nucleus.

b)

Mitosis results in diploid (2n) daughter cells and Meiosis results in haploid (n) daughter cells.

c)

Mitosis results in 2 daughter cells and Meiosis results in 4 daughter cells.

d)

Mitosis makes somatic (body) cells and Meiosis makes gametes (egg and sperm cells).
