Interphase
Interphase is the initial stage of mitosis in which the cell prepares for cell division. The cell increases in size and makes a copy of its DNA, or genetic code.
Prophase
In prophase, the genetic information inside the cell condenses to form chromosomes, which become visible. The membrane of the cell's nucleus also dissolves. The cell will have double the number of chromosomes in chromatids -- if the cell has eight chromosomes, it will have 16 chromatids.
Metaphase
In metaphase, the chromosomes align in the middle of the cell in preparation to be separated out into a daughter cell.
Anaphase
During anaphase, the chromatids separate and the number of chromosomes inside the cell doubles. The chromosomes also separate in anaphase.
Telophase
Telophase marks the beginning and end of the cell's physical division into two cells. The nucleus of the cell reforms, restoring the membrane that disintegrated during prophase. The chromosomes also uncoil during telophase.
Final Stage
After telophase, there are two resulting cells -- the parent cell and the daughter cell. Because mitosis is an asexual form of cell reproduction, only one parent cell contributes its genetic material to the daughter cell. This means the daughter cell is an exact genetic copy of the parent cell. In the event that the process of mitosis are disrupted or a bad copy is made of the parent cell's genetic material, the daughter cell may undergo spontaneous apoptosis, or cell death, to prevent cellular damage to the organism as a whole.
