Answer 4

Prophase

Question 5

In which stage of mitosis/the cell cycle does DNA replicate?

Answer 5

Interphase

Question 6

In which stage of mitosis/the cell cycle do replicated strands move toward opposite poles?

Answer 6

Anaphase

Question 7

In which stage of mitosis/the cell cycle do the chromosomes form a line across the middle of the cell (the equatorial plate)?

Answer 7

Metaphase

Question 8

In which stage of mitosis/the cell cycle does the nuclear membrane form around each set of chromosomes?

Answer 8

Telophase

Question 9

In which stage of mitosis/the cell cycle does the cell grow?

Answer 9

Interphase

Question 10

In which stages of mitosis (including interphase) is the nucleus present?

Answer 10

Interphase, prophase, and telophase.

Question 11

In which stages of mitosis (including interphase) is the nucleolus present?

Answer 11

Interphase, prophase, and telophase.

Question 12

In which stages of mitosis (including interphase) is the nuclear membrane present?

Answer 12

Interphase, telophase, and somewhat visible in prophase (but beginning to disassemble)

Question 13

In which stages of mitosis (including interphase) are the chromatin visible?

Answer 13

Interphase and telophase.

Question 14

In which stages of mitosis (including interphase) are the chromosomes present?

Answer 14

Prophase, metaphase and anaphase.

Question 15

In which stages of mitosis (including interphase) are the spindle fibres present?

Answer 15

Prophase, metaphase and anaphase.

Question 16

What is one main difference in cell division in a plant cell vs. an animal cell?

Answer 16

In cytokinesis, a new cell wall forms in a plant cell between the two new nuclei of the daughter cells, whereas the existing cell membrane of an animal cell pinches off (creating a furrow).

Question 17

What is the end result of mitosis (including cytokinesis)?

Answer 17

Then end result is complete and equal division of the nucleus, with two new daughter cells containing identical genetic information to the parent cell.

Question 18

Describe how the cell prepares for mitosis.

Answer 18

It doubles its chromosomes and grows.

Question 19

What happens to the cell during interphase?

Answer 19

The cell grows, making protiens, producing wastes and doubling chromosomes.

Question 20

During mitosis, in which stage do the centromeres divide?

Answer 20

Anaphase.

Question 21

In which mitosis stage do the centrioles move to opposite ends of the cell?

Answer 21

Prophase

Question 22

In which step of mitosis does the nuclear membrane form around each mass of chromosomes?

Answer 22

Telophase.

Question 23

In which step of mitosis do the chromosome strands separate toward opposite ends of the cell?

Answer 23

Anaphase

Question 24

In which step of mitosis are copies of each chromosome made?

Answer 24

Interphase

Question 25

In which step of mitosis does the cell membrane pinch together and the cytoplasm of the cell divide?

Answer 25

Cytokinesis

Question 26

In which step of mitosis does the nuclear membrane disappear?

Answer 26

When in the cell cycle do the microtubules of the cytoskeleton (responsible for the cell’s shape, movement/motility and attachment to other cells) disassemble?

Answer 34

Prophase

Question 35

When in the cell cycle are microtubules used to grow the mitotic spindle from the region of the centriole?

Answer 35

Prophase
