Mitosis

The main change stage of a cell-division cycle in which a cell is divided into two new but genetically identical cells, each containing the same number of chromosomes. The process of mitosis is carried out in four main stages: prophase, metaphase, anaphase, and finally telophase. The other stages of the cell-division cycle are the initial interphase and the final phase of division called cytokinesis, which usually occurs during the telophase stage, separating the two split nuclei into the two new cells.
