Detailed explanation-1: -During anaphase, the sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell.

Detailed explanation-2: -Anaphase. The sister chromatids separate from one another and are pulled towards opposite poles of the cell. The microtubules that are not attached to chromosomes push the two poles of the spindle apart, while the kinetochore microtubules pull the chromosomes towards the poles.

Detailed explanation-3: -Anaphase is the fourth step in mitosis. In anaphase, cohesin proteins binding the sister chromatids together break down. sister chromatids (now called chromosomes) are pulled toward opposite poles.

Detailed explanation-4: -Metaphase follows prophase. During metaphase, the chromosomes align in the center of the cell at the equatorial plate and the spindle fibers attach to the centromeres of the chromosomes.

Detailed explanation-5: -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.
