The rest of the cell may then continue to divide by cytokinesis to produce two daughter cells. The result is two genetically identical daughter nuclei. During mitosis, the chromosomes, which have already duplicated, condense and attach to spindle fibers that pull one copy of each chromosome to opposite sides of the cell. These stages are preprophase (specific to plant cells), prophase, prometaphase, metaphase, anaphase, and telophase. The process of mitosis is divided into stages corresponding to the completion of one set of activities and the start of the next. The different stages of mitosis altogether define the mitotic ( M) phase of a cell cycle-the division of the mother cell into two daughter cells genetically identical to each other. In general, mitosis is preceded by S phase of interphase (during which DNA replication occurs) and is often followed by telophase and cytokinesis which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components. Therefore, mitosis is also known as equational division. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes is maintained. In cell biology, mitosis ( / m aɪ ˈ t oʊ s ɪ s/) is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei.
