If a cell has 8 chromosomes at metaphase of mitosis, how many chromosomes will it have during anaphase?
Correct answer: D. 16
- A. 2
- B. 4
- C. 8
- D. 16
Explanation
During anaphase of mitosis, the sister chromatids separate and move towards opposite poles of the cell. Each chromatid is considered a chromosome. So if a cell has 8 chromosomes (each consisting of 2 sister chromatids) at metaphase, during anaphase, each sister chromatid will be pulled apart. Therefore, the cell will have 16 chromosomes during anaphase.
