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: -In metaphase II, the chromosomes line up individually along the metaphase plate. In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.
Detailed explanation-4: -Cell Biol. https://doi.org/10.1083/jcb.201807228) show that chromosome alignment ensures mitotic fidelity by promoting interchromosomal compaction during anaphase. During mitosis, chromosomes align at the spindle equator to establish a metaphase plate.
