Detailed explanation-1: -Anaphase. After metaphase is complete, the cell enters anaphase. During anaphase, the microtubules attached to the kinetochores contract, which pulls the sister chromatids apart and toward opposite poles of the cell (Figure 3c). At this point, each chromatid is considered a separate chromosome.

Detailed explanation-2: -Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate.

Detailed explanation-3: -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-4: -Anaphase (from Ancient Greek -(ana-) ‘back, backward’, and (phásis) ‘appearance’) is the stage of mitosis after the process of metaphase, when replicated chromosomes are split and the newly-copied chromosomes (daughter chromatids) are moved to opposite poles of the cell.

Detailed explanation-5: -The anaphase stage of mitosis is the specific stage where the centromere breaks so that the two sister chromatids can move towards the poles. This movement occurs with the help of spindle fibers and then the two sister chromatids move to the two opposite poles in the dividing cell.
