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

Detailed explanation-4: -In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein “glue” that holds the sister chromatids together is broken down, allowing them to separate. Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell.

Detailed explanation-5: -During anaphase, the sister chromatids separate and begin to migrate to opposite poles of the cell, and a cleavage furrow begins to develop.
