Detailed explanation-1: -Cell division occurs during M phase, which consists of nuclear division (mitosis) followed by cytoplasmic division (cytokinesis). The DNA is replicated in the preceding S phase; the two copies of each replicated chromosome (called sister chromatids) remain glued together by cohesins.
Detailed explanation-2: -The M phase consists of mitosis and cytokinesis. Mitosis is the process in which DNA condenses into visible chromosomes, which is followed by the separation of the chromosomes into two identical sets.
Detailed explanation-3: -In cytokinesis, the cytoplasm of the cell is split in two, making two new cells. Cytokinesis usually begins just as mitosis is ending, with a little overlap. Importantly, cytokinesis takes place differently in animal and plant cells. Cytokinesis in animal and plant cells.
Detailed explanation-4: -Cytokinesis begins in anaphase and ends in telophase, reaching completion as the next interphase begins. The first visible change of cytokinesis in an animal cell is the sudden appearance of a pucker, or cleavage furrow, on the cell surface.
