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: -Spindle fibers align the chromosomes along the middle of the cell nucleus. This line is referred to as the metaphase plate.
Detailed explanation-3: -Metaphase (the shortest phase of mitosis) is characterized by two events: Chromosomes line up across the middle of the cell. Spindle fibers connect the centromere of each sister chromatid to the poles of the cell.
