Detailed explanation-1: -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.

Detailed explanation-2: -During metaphase, the cell’s chromosomes align themselves in the middle of the cell through a type of cellular “tug of war.” The chromosomes, which have been replicated and remain joined at a central point called the centromere, are called sister chromatids.

Detailed explanation-3: -During the metaphase stage of mitosis, the sister chromatids line up at the metaphase plate. During the metaphase stage, all the sister chromatids are bound to the spindle fibers. The spindle fibers are directly attached to the centromeres and that is why they are aligned at the equatorial region of the cell.

Detailed explanation-4: -Metaphase chromosomes Metaphase is the stage of mitosis in which the chromosomes align on the equatorial plate.
