WebThe centromere of each chromosome splits, and the two sister chromatids are pulled to opposite poles of the cell by the mitotic spindle. This is facilitated by the hydrolysis of a protein called cohesin, which holds the sister chromatids together. Finally, in telophase, the fourth and final stage of mitosis, the two daughter cells are formed.
