The document summarizes the stages of the cell cycle: Interphase where the cell grows and chromosomes copy, followed by Prophase where the nuclear envelope breaks down. During Metaphase chromosomes line up in the middle, then during Anaphase chromosomes are pulled apart. Telophase involves the formation of new nuclei, and finally Cytokinesis divides the cell into two daughter cells.

2. Interphase Prophase Cytokinesis Telophase Anaphase Metaphase The Cell Cycle End Show

3. Interphase The cell matures and the chromosomes copy themselves. Back

4. Prophase The nuclear membrane disappears and spindle fibers form at the poles of the cell. Back

5. Metaphase The chromosomes line up at the middle and two spindle fibers attach to catch chromosome pairs. Back

6. Anaphase Chromosome pairs split and the fiber strands pull the chromosomes to each pole. Back

7. Telophase 2 New nuclei form at two poles of the cell where chromosomes have gathered. Now mitosis is complete and the cell membrane pinches in. Back

8. Cytokinesis Two new daughter cells are formed. Back
