Detailed explanation-1: -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-2: -Anaphase II is the stage when sister chromatids of every chromosome separate and begin to move towards the opposite ends of the cell. The separation and the movement is due to the shortening of the kinetochore microtubules.

Detailed explanation-3: -Sister chromatids separate during anaphase in a three-stage program as directed by interaxis bridges.

Detailed explanation-4: -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-5: -Answer and Explanation: During meiosis, the sister chromatids separate from each other during anaphase II, during the second division of meiosis. In meiosis I, the homologous pairs of chromosomes are separated from each other, leaving haploid cells with duplicated chromosomes.
