| Cell Cycle | ordered set of events resulting in cell growth and the division of one cell into 2 daughter cells. Period of time: from beginning of one cell division to beginning of the next |
| Interphase | cell grows in size and doubles its content by copying its chromosomes. It includes G1, S, and G2 phases |
| Prophase | first phase of mitosis and the longest phase. DNA goes from string-like chromatin to chromosomes |
| Metaphase | second stage of mitosis and the shortest. Chromosomes complete attachment to the spindle. Chromosomes line up across center of cell between 2 pairs of centrioles |
| Anaphase | third stage if mitosis; centromeres that hold together. Chromotids split, allowing sister chromatids to separate. One chromatid goes to one pole, and the other goes to the other pole |
| Telophase | fourth stage of mitosis; oppoite of prophase. Mitotic spindle breaks apart and disappears. The nuclear membrane re-forms, forming 2 distimce nucleii |
| Cytokinesis | dividing of the cytoplasm, dreating 2 identical cells |
| Cyclins | protein, whose amounts vary during the cell cycle, therefore regulating the timing of the cell cycle |
