Detailed explanation-1: -Metaphase is a stage during the process of cell division (mitosis or meiosis). Normally, individual chromosomes are spread out in the cell nucleus. During metaphase, the nucleus dissolves and the cell’s chromosomes condense and move together, aligning in the center of the dividing cell.

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: -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.

Detailed explanation-4: -Metaphase is a stage of cell division where the chromosomes line up along the metaphase plate. The metaphase plate is an imaginary line that runs across the cell, dividing the cell into hemispheres. As the chromosomes line up here, they begin to separate into individual chromatids and are drawn towards opposite poles.

Detailed explanation-5: -Metaphase II: The paired chromosomes line up. Anaphase II: The chromatids split at the centromere and migrate along the spindle fibers to opposite poles.
