can you define the different phases of mitosis in cell distribution ? 

  • Mitosis and cytokinesis together define the mitotic (M) phase of the cell cycle.
  • Mitosis knows as equational division, because, eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two daughter nuclei. Mitosis is followed by cytokinesis (division of cell into two daughter cells with equal cellular components). Mitosis is divided into following four stages.

The mitotic phases are:

  • Prophase: The two chromatids remain attached to centromere, the nuclear envelope break down and disappear, prophase the spindle begins to form, the centrioles separate and move apart and asters appear around them.
  • Metaphase: The chromosomes congregate at an equatorial plane midway between the two ends to which the spindle tapers. The chromatids are attached to the spindle fibers at the centromeres.
  • Anaphase: The two chromatids of each chromosome separate and move to opposite poles, as if pulled along the spindle fibers by the centromeres.
  • Telophase: New nuclear envelopes form around the two groups of daughter chromosomes the new nucleoli begin to appear, the formation of the two daughter nuclei is completed and the spindle fibers disappear.

Cytokinesis: Separates the daughter nuclei into two new individual daughter cells.
