Anaphase I:The chromatids separate and move to opposite polesAnaphase II:The centromeres separate and the sister chromatids move toward the opposite poles of the cell.

Detailed explanation-1: -During anaphase 1, homologous chromosomes separate and move to opposite ends of the cell. With anaphase 2, the sister chromatids separate in much the same manner as mitotic anaphase. Because the separation of genetic material occurs during anaphase, this step needs to be tightly regulated.
Detailed explanation-2: -During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle.
Detailed explanation-3: -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.
Detailed explanation-4: -In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.
