Detailed explanation-1: -The sister chromatids are pairs of identical copies of DNA joined at a point called the centromere. 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-2: -Sister chromatids separate during anaphase in a three-stage program as directed by interaxis bridges.
Detailed explanation-3: -In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.
Detailed explanation-4: -Separation of the paired sister chromatids is required for poleward motion in anaphase. Chromatid separation results from the proteolytic degradation of components that link the chromatids at the centromere.
