3 Table 2: Events in the Stages of the Mitotic Cell Cycle Overall Stage of the Mitotic Cell Cycle Specific Stage of the Mitotic Cell Cycle Events 1. Metabolic Cell (non-dividing cell) Interphase general cell growth & DNA replication 2. Cell Divison Prophase nuclear membrane disappears, nucleolus disappears, chromatin condenses into chromosomes, spindle apparatus forms Mitosis (PMAT) (separation of genetic materials) Metaphase chromosomes line up in metaphase plate (centromere splits to end metaphase/begin anaphase) and Anaphase sister chromatids (now = separate chromosomes) are pulled to the opposite poles by the spindle apparatus Cytokinesis (division of the cytoplasm into 2 cells) Telophase chromosomes reach the opposite poles and clump; events of prophase are reversed (chromosomes to chromatin, nucleolus and nuclear membrane reform, spindle apparatus dismantled); cytokinesis is completed 3
