Explain the process of mitosis

The process of mitosis produces 2 genetically identical daughter cells. It can be remembered using the acronym PMAT.Prophase: Chromatin supercoils and condenses into chromosomes (which are now visible). The nucleolus disappears and nuclear membrane breaks down. Centrioles migrate to opposite poles and spindle fibres start to formMetaphase: Chromosomes line up their centromeres on the equator of the cell and centromeres attach to spindle fibres.Anaphase: Spindle fibres 'contract' and shorten, centromeres are split and pulled apart. Chromatids are pulled to each pole (so there is one chromatid from each chromosome on each side of the equator).Telophase: The chromosomes are now separate and ready to form cells. The uncoil (and are now not visible anymore). The nucleus, nucleolus and nuclear membrane reform and organelles are distributed evenly.Cytokinesis: The separation of the cell membrane, and 2 identical daughter cells have now been formed.
