Cell Cycle

Question 1

What are the four phases of mitosis, in the correct order?

Answer 1

Prophase, metaphase, anaphase, telophase

Question 2

Describe one event that happens during prophase.

Answer 2

chromatin condense and shorten into visible chromosome

Question 3

Describe one event that happens during metaphase.

Answer 3

chromatid pairs align in the centre of the mitotic spindle, along the middle of the cell.

Question 4

Describe one event that happens during anaphase.

Answer 4

the centromeres split, separating the two members of the chromatid pair and move to the opposite poles of the cell

Question 5

Describe one event that happens during telophase.

Answer 5

chromosomes uncoil and revert back to chromatins; mitotic spindle breaks up and the nucleus reappears

Question 6

Describe one event that happens during interphase.

Answer 6

replication of cells organelles and cytosolic components occur; replication of chromosomes occur

Question 7

Genetic recombination occurs during which phase?

Answer 7

Prophase I

Question 8

How many chromosomes are in a haploid cell at the completion of meiosis?

Answer 8

23
