Transcript
Before this division takes place Cytokinesis occurs after the end a cell must copy its own set of of mitosis, when the cell chromosomes. physically splits in two to create two new ‘daughter’ cells. DNA replicates! Two identical cells form! The cell begins to physically divide. The chromosomes are at the poles of the cell. The nuclear envelope reforms around the two sets of chromosomes. Chromosomes line up in the middle – at the metaphase plate (equator) of cell. centromeres. DNA condenses. Chromosomes become visible. Nuclear envelope disappears. Spindle Forms. pull sister chromatids to opposite ends of cell. Each chromosome goes from having 2 sister chromatids to being 2 separate chromosomes. Mitosis is the process that all normal body cells (somatic cells) use to divide into two new ‘daughter’ cells. This is used for growth, maintenance and repair.
