Detailed explanation-1: -During anaphase II, microtubules from each spindle attach to each sister chromatid at the kinetochore. The sister chromatids then separate, and the microtubules pull them to opposite poles of the cell.

Detailed explanation-2: -In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.

Detailed explanation-3: -Anaphase II: The chromatids split at the centromere and migrate along the spindle fibers to opposite poles. Telophase II: The cells pinch in the center and divide again. The final outcome is four cells, each with half of the genetic material found in the original.

Detailed explanation-4: -Anaphase. The shortest stage of mitosis. The centromeres divide, and the sister chromatids of each chromosome are pulled apart-or ‘disjoin’-and move to the opposite ends of the cell, pulled by spindle fibres attached to the kinetochore regions.

Detailed explanation-5: -Anaphase I begins when homologous chromosomes separate. The nuclear envelope reforms and nucleoli reappear. The chromosomes coil up, the nuclear membrane begins to disintegrate, and the centrosomes begin moving apart. Spindle fibers form and sister chromatids align to the equator of the cell.
