Mitosis is only one section of the life cycle of a cell. . Interphase is the main part of the cell cycle. This is where DNA is replicated (a copy is made) to prepare for mitosis.. Overview. Cytokinesis. 01-08-09. http://www.cellsalive.com/mitosis.htm. Cell Division. The division of eukaryotic cells occurs in two main stages. Mitosis is the first stage. Is the process by which the nucleus of the cell is divided into two nuclei, each with the same number and kinds of chromosomes as the parent cell. Be sure to turn in any labs from yesterday. . .
