The document describes the stages of the cell cycle: Interphase where the cell grows and chromosomes are copied, prophase where the nuclear envelope breaks down and spindle fibers form, metaphase where chromosomes line up in the middle, anaphase where chromosomes are pulled to opposite poles, telophase where new nuclei form and cytokinesis where the cell membrane pinches to form two daughter cells.

1. Cell Cycle Kaylee Hettenbaugh Start the Tour

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

3. Interphase Cell mature. Chromosomes copy themselves. Back

4. Prophase Nuclear membrane disappears. Spindle fibers form at the polls of a cell. Back

5. Metaphase Chromosomes line up at the middle. 2 spindle fibers attach to each chromosome pair. Back

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

7. Telophase 2 new nuclei form at 2 poles of a cell were chromosomes have gathered. Mitios is complete. Cell membrane pinched in. Back

8. Cytokinesis 2 new daughter cells are formed. Back
