The document summarizes the stages of the cell cycle: 1) Interphase is when the cell grows and copies its DNA in preparation for division. 2) Prophase is when the nuclear membrane disappears and spindle fibers form. 3) Metaphase is when chromosomes line up in the middle and attach to spindle fibers. 4) Anaphase is when chromosomes separate and move to opposite poles. 5) Telophase is when two new nuclei form and mitosis is complete. 6) Cytokinesis is when the cell membrane pinches together to form two daughter cells.

1. Cell Cycle Samantha Ecker Start the Tour

2. Interphase Prophase Cytokinesis Telophase Anaphase Metaphase The Cell Cycle

3. Interphase The cell grows to the mature size Makes a copy of its DNA Chromosomes copies themselves Back

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

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

6. Anaphase Chromosomes pair 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 together Back

8. Cytokinesis Two new daughter cell are formed. Back
