Cell Cycle Interphase: Period between cell divisions. Cell doubles its original size. All normal cell functions occur. No cell division happens. Chromosomes are duplicated during this phase. DNA is found in chromosomes. Mitosis Process by which cells reproduce Happens by dividing the nucleus & cytoplasm and duplicating chromosomes 4-step process (PMAT) Step 1: Prophase Nuclear membrane begins to disappear. Step 2: Metaphase Pairs of chromosomes line up in the middle of the cell. Step 3: Anaphase Pairs of chromosomes split apart. Step 4: Telophase Last stage of mitosis. Furrow forms in the middle of the cell to complete the dividing of the cell. Cytokinesis Cell division is complete. Results in two (daughter) cells.
