Explanation:
Detailed explanation-1: -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-2: -During metaphase, chromosomes come together at the equator line because of the mitotic spindle fibers. These fibers emerge from the centrosome present at each pole of the cell.
Detailed explanation-3: -In Anaphase of mitosis: (I) Chromosomes move to equator and get aligned along metaphase plate.
