Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The stage of mitosis where the sister chromatids separate:
A
prophase
B
anaphase
C
telophase
D
metaphase
Explanation: 

Detailed explanation-1: -Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell. Enzymatic breakdown of cohesin-which linked the sister chromatids together during prophase-causes this separation to occur.

Detailed explanation-2: -Anaphase II: During anaphase II, the centromere splits, freeing the sister chromatids from each other. At this point, spindle fibers begin to shorten, pulling the newly-separated sister chromatids towards opposite ends of the cell.

Detailed explanation-3: -Sister chromatids separate during anaphase in a three-stage program as directed by interaxis bridges.

Detailed explanation-4: -In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.

Detailed explanation-5: -Sister chromatids separate during anaphase I.
