WebMetaphase is the second stage of mitosis after prophase and is followed by anaphase. In mitosis, the duplicated genetic material is carried from the nucleus of the parent cell to the two identical daughter cells. During metaphase, chromosomes move to the equator, and this region is known as the metaphase plate. WebThe chromosomes begin to decondense and return to their “stringy” form. Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly … In mitosis, the nuclear DNA of the cell condenses into visible chromosomes … A centromere is the central region of a chromosome itself, while the …
