| Mitosis | cell division |
| chromosome | coiled DNA |
| G1 Phase | cell growth |
| S Phase | DNA replication |
| G2 Phase | prepare for mitosis |
| Interphase | longest part of cell cycle |
| Prophase | lst phase of mitosis; DNA forms chromosomes; nuclear envelope disappears; spindle fibers form |
| Metaphase | sister chromatids line up in middle of cell |
| Anaphase | sister chromatids separate; move towards opposite poles |
| Telophase | nuclear envelope reappears; chromosomes uncoil; |
| Cytokinesis | division of cytoplasm |
| sister chromatids | identical chromosomes which pair up in prophase and separate in anaphase |
| cancer cells | cells which have begun to divide contiually and do not respond to cell cyclins |
| cell cyclins | molecules which regulate cell cycles |
