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. Yvonne Norman. Edited By: . Ms. .
