alleryWhat happens to sister chromatids during anaphase?
Athey separate at the centromere; pulled to poles
Bthey fuse into a single chromosome
Cthey decondense and become invisible
Dthe nuclear membrane re-forms around them
Answer & Solution
Correct answer: A. they separate at the centromere; pulled to poles
Anaphase is defined by the separation of sister chromatids at the centromere, pulled toward opposite poles by spindle fibres.
Decondensation and nuclear membrane re-formation belong to telophase.
