Process where a cell splits into two identical daughter cells. It occurs it two main phases.
-Mitosis - division of the nucleus
-Cytokinesis - division of the cytoplasm |

| second phase of mitosis, spindle fibers line up the sister chromatids in the center of the cell |

Definition
| third phase in mitosis, sister chromatids separate at their centromeres. They become individual chromosomes. The spindle fibers move the separated chromosomes to opposite sides of the cell. |

| fourth phase in mitosis, 2 nuclear envelopes form around each set of chromosomes, spindle fibers break down. Cell divides into 2 identical daughter cells. |
