The nucleoli and nuclear membranes reform and the two groups of chromosomes uncoil to reform chromatin as the spindle which separated them during anaphase breaks down in, for ten points, what stage of mitosis?
During this stage, the spindle asters define the position of the contractile ring and thus the plane of cytokinesis.
