Question

In which phase of mitosis can you count the chromosomes?

Answer 1

I would consider anaphase.

Explanation:

In anaphase, the pairs of sister chromatids separate and are now individual chromosomes. In anaphase, we can see the individual chromosomes moving to opposite poles of the cell. You can count the chromosomes at this point if you have high enough magnification.

Be aware, though, that each set of chromosomes moving to opposite poles represents the diploid number of chromosomes(46 in humans). So in humans, mitosis begins with 46 pairs of sister chromatids, for a total of 92 chromosomes, which separate during anaphase into two sets of 46 chromosomes being pulled to opposite poles of the cell.
