Mitosis occurs during the M phase of the cell life cycle. It is defined as nuclear division without genetic change. Mitosis has four stages: prophase, metaphase, anaphase, and telophase. The process varies for different eukaryotes. 

Prophase - the chromatin condensates into chromosomes, the nuclear envelope breaks down, centrioles move to opposite ends of the cells, the spindle apparatus begins to form consisting of aster, centromeres, and spindle microtubules.

Metaphase - chromosomes align along the midline of the cell

Anaphase - sister chromatids split at their attaching centromeres, and move to opposite ends of the cell. Cytokinesis may start towards the end of this phase

Telophase - the nuclear membrane reforms, as well as the nucleolus, chromosomes decondense. Cytokinesis continues
