Mitosis

• Prophase: DNA normally in the form of chromatin (two

identical copies - sister chromosomes) attached to each other

by centromere.

• Metaphase: begin to line up in the middle of the cell.

• Anaphase: the chromosomes lined up along the middle of the

spindle

• Telophase: nuclear membrane reforms around the genetic

material

• Cytokinesis or cleavage: the cellular membrane pinches off

between the two newly separated nuclei, to form two new

daughter cells.
