the nucleus. Also, each of the new daughter cells now has one of the two centrosomes that were formed during interphase. The chromosomes are not condensed anymore; they are long and stringy.
Cytokinesis is when the daughter cells have completely separated into two daughter cells. This can begin in the earlier phases of mitosis. The two daughter cells have been formed as the spindles elongate the cell. A clevage furrow forms and that is the dividing line between the two new cells.
