What is the mitosis phase in a cell cycle and what are the phases of mitosis phase?

Mitosis phase is a short period of cell cycle when chromosome is separated to facilitate a complete cell division. There are mainly 4 phases in mitosis phase:

• Prophase: Chromatin condenses into chromosomes and nuclear envelope disappears.
• Metaphase: The pairs of condensed chromosomes line up along the equator of the elongated cell.
• Anaphase: The sister chromatids are drawn to opposite poles (ends) of the elongated cell and the chromosomes are split apart.
• Telophase: The chromosomes are at the poles and are becoming more diffuse. The nuclear envelope is reforming, and the cytoplasm may be dividing.

After telophase, the genetic contents of one cell have been divided equally into two cells. However, cell division is not complete until cytokinesis takes place, which is not a phase of mitosis but necessary for completing cell division. Cytokinesis starts before anaphase ends and completes shortly after telophase, which divides the cell’s cytoplasm and results in irreversible separation leading to two daughter cells.
