In eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes. All of the organelles duplicate.
a part of the cell's life cycle in which the cell grows, the DNA is copied, and the organelles duplicate.
a part of the cell's life cycle in which the nuclear membrane disappears and the chromosomes form
a part of the cell's life cycle in which the chromosomes line up in the center of the cell and the spindle fibers form
the opposite of the prophase;the nuclear membrane re-forms, the chromosomes un-coil, and the cell has two nuclei
