PPT-Mitosis by Vijayshree Hemke

INTRODUCTION Mitosis is the final phase of the cell cycle It is a relatively short phase Mitosis occupies approx 10 of the total cell cycle time of a typical human proliferative cell In M phase actual cell division or mitosis occurs. The cell cycle. 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..

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. Notebook Page 12. Warm . Up & Spiral. 2/23/2017.
