During Which Phase of Mitosis Do the Chromatids Become Chromosomes

Question

During which phase of mitosis do the chromatids become chromosomes?
A) telophase
B) anaphase
C) prophase
D) metaphase
E) cytokinesis

Accepted Answer

During telophase, the chromatids that were pulled apart during anaphase reach the opposite poles of the cell and de-condense, forming two new nuclei. At this point, each chromatid is considered a separate chromosome, marking the end of mitosis and leading into cytokinesis.
