Interphase: the DNA of the chromosomes replicate.
Prophase: each chromosome has a two part structure consisting of sister chromatids joined by a
centromere.
Metaphase: the chromosomes randomly align at the metaphase plate perpendicular to the spindle. Also
at metaphase the centromeres duplicate.
Anaphase: the sister chromatids are pulled to opposite poles of the cell by the spindle fibers.
Telophase: the separated sets of chromosomes become enclosed in a nuclear membrane.
Cytokinesis will complete the mitotic division. The two cells that are the result of this mitotic division are
genetically identical to the original cell at the left.
