WebThis is called the “telophase.”. Once the new membranes encircle each set of chromosomes, they begin to uncoil and the cell walls in the middle start to “pinch” in a process called cell cleavage or “cytokinesis” so that it closes off and creates two new cells. The two new cells that result from mitosis are called “diploids.”.
