interphase
cell grows to twice the size
changes that occurr in interphase prepare a cell for divisions and the DNA is duplicated
prophase
chromatin in the neucleus condenses into chromosones
metaphase
chromosones line up n the middle of the cell
anaphase
chromatids of each chroma sones are pulled to the opposite side
telophase
a new nuclear membrane forms around each group of chromosones and they start to unwind and the fibers disappear
cytokenesis
2 new cells
