Question

If a cell normally has 12 chromosomes, how many chromosomes are present in anaphase of the cell cycle?

A. 6

B. 12

C. 24

D. more than 12 but fewer than 24

E. None of the above.

Answer 1

In anaphase of the cell cycle of a cell that normally has 12 chromosomes, 24 chromosomes would be present as the sister chromatids separate.

Step-by-step explanation:

If a cell normally has 12 chromosomes, during anaphase of the cell cycle, the number of chromosomes present would be 24. This is because anaphase is the stage in mitosis where the sister chromatids are pulled apart to opposite ends of the cell, each becoming an individual chromosome. Since each original chromosome consists of two sister chromatids, the separation doubles the number of chromosomes.
