Scientists divided the stages of mitosis into four phases: prophase, metaphase, anaphase, and telophase. Depending on the type of cell, mitosis may last anywhere from a few minutes to several days.

The steps of mitosis can be easily remembered using the acronym, PMAT. Each of the letters in the acronym stands for a different phase.

Cytokinesis

As a result of mitosis, two nuclei, each with a duplicate set of chromosomes, are formed. All that remains to complete the M phase of the cycle is cytokinesis, the division of the cytoplasm. Cytokinesis usually occurs at the same time as telophase.

Once cytokinesis is complete, two new daughter cells are formed. Each new daughter cell will enter into interphase.
