Detailed explanation-1: -During metaphase, the kinetochore microtubules pull the sister chromatids back and forth until they align along the equator of the cell, called the equatorial plane. There is an important checkpoint in the middle of mitosis, called the metaphase checkpoint, during which the cell ensures that it is ready to divide.
Detailed explanation-2: -Chromosomes, consisting of sister chromatids, line up at the equator or middle of the cell during metaphase.
Detailed explanation-3: -There are 46 individual chromosomes in each cell. Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate.
Detailed explanation-4: -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-5: -Metaphase follows prophase. During metaphase, the chromosomes align in the center of the cell at the equatorial plate and the spindle fibers attach to the centromeres of the chromosomes.
