The document describes the stages of the cell cycle: Interphase where the cell grows and chromosomes are copied, followed by prophase where the nuclear envelope breaks down. Metaphase where chromosomes line up in the middle, then anaphase where chromosomes are pulled apart. Telophase forms two new nuclei, and finally cytokinesis divides the cell into two daughter cells.

1. Cell Cycle Andrew Hvizdzak Start the Tour

2. Interphase Prophase Cytokinesis Telophase Anaphase Metaphase The Cell Cycle

3. Interphase About 90% of cell cycle time Cell matures Chromosomes copy themselves Back

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

5. Metaphase Chromosomes line up in the middle 2 spindle fibers attach to each chromosome pair 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 Mitosis is complete Cell membrane pinches in Back

8. Cytokinesis Two new daughter cells are formed Back
