Detailed explanation-1: -Chromosomes, consisting of sister chromatids, line up at the equator or middle of the cell during metaphase.

Detailed explanation-2: -Anaphase is the shortest phase of mitosis. In anaphase, the sister chromatids are pulled apart to opposite ends of the cell. In metaphase, chromosomes line up along the metaphase plate.

Detailed explanation-3: -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-4: -In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell.

Detailed explanation-5: -Metaphase. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
