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: -Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate.
Detailed explanation-3: -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.
