WebThe stages of mitosis are: prophase, metaphase, anaphase and telophase. Only two pairs of chromosomes are shown in the diagrams below. There are 23 pairs of chromosomes … WebInterphase. Within multicellular organisms, not all cells retain the ability to divide. Eukaryotic cells that do retain the ability to divide show a cell cycle. Mitosis is part of a precisely controlled process known as the cell cycle. The cell cycle is the regulated sequence of events that occurs between one cell division and the next.
