Introducing the Cell Cycle. The eukaryotic cell cycle is divided into four phases, designated G 1, S, G 2, and M respectively (see the figure to the right). Collectively, the G 1, S, and G 2 phases are referred to as interphase (designated I in the figure), and take up approximately 90% of the cell's lifespan.ntroducing the Cell Cycle.

For eukaryotic cells containing extensive cell cycle checkpoint controls, the duration of mitosis is somewhat independent of the total length of the cell cycle, and depends on the size of the cell. Yeast: Cell cycle takes ~100 minutes, mitosis takes ~20 minutes. Chicken cells (DT40 line): Cell cycle ~8 hours, mitosis ~30 minutes.
