Anaphase II and anaphase of mitosis

Detailed explanation-1: -During anaphase (b), the sister chromatids are pulled apart and move toward opposite poles of the cell.
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: -Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell.
Detailed explanation-4: -Sister chromatids separate during anaphase in a three-stage program as directed by interaxis bridges.
Detailed explanation-5: -Anaphase II is the stage when sister chromatids of every chromosome separate and begin to move towards the opposite ends of the cell. The separation and the movement is due to the shortening of the kinetochore microtubules.
