Question
If a cell has 8 chromosomes at metaphase of mitosis, how many chromosomes will it have during anaphase? a. 16 b. 8 c. 2 d. 4
Correct Answer
Option A is the correct answer.
Detailed Explanation
At metaphase, each of the 8 chromosomes consists of two sister chromatids. During anaphase, the sister chromatids separate, and each becomes an independent chromosome. So, as they move to opposite poles, each pole receives 8 chromosomes, and the total number of chromosomes in the cell (if you count both forming daughter nuclei) is temporarily 16.
Hint
Count each chromatid as a separate chromosome once they split.
