chromatin condenses, spindle forms, nuclear membrane disappears.
sister chromatids line up on the equator of the cell.
sister chromatids are pulled apart at the centromere and chromosomes are pulled to opposite poles of the cell.
cytokinesis (cell divides into two new daughter cells), chromosomes decondense, spindle disappears, nuclear membrane reforms.
