The document summarizes the stages of the cell cycle: 1) Interphase is when the cell grows and copies its DNA in preparation for division. 2) Prophase is when the nuclear membrane disappears and spindle fibers form. 3) Metaphase is when chromosomes line up in the middle and attach to spindle fibers. 4) Anaphase is when chromosomes separate and move to opposite poles. 5) Telophase is when two new nuclei form and mitosis is complete. 6) Cytokinesis is when the cell membrane pinches together to form two daughter cells.
