Mitosis and Meiosis and Cell Cycle

1.      The centromere is a region in which…

The answer is chromatids are attached to one another

2.      What is a chromatid?

A replicated chromosome

3.      During which phase do centioles begin to move apart in animal cells

Prometaphase

4.      Which phase is the longest phase of the mitotic stages?

Prophase

5.      During which phase do centromeres uncouple, sister chromatids are separated, and the two new chromosomes move to opposite poles of the cell?

Anaphase

6.      A cell containing 92 chromatids at metaphase of mitosis would, at its completion, produce two nuclei containing how many chromosomes?

46

7.      The formation of a cell plate is beginning across the middle of a cell and nuclei are re-forming at opposite ends of the cell. What kind of cell is this?

A plant cell undergoing cytokinesis

8.      Movement of the chromosomes during anaphase would be most affected by a drug that…

Prevents shortening of microtubules
