During interphase, the cell is preparing to divide and is actively synthesizing the required components. Originally and inaccurately referred to as the resting stage, the interphase is actually a period in which a considerable degree of activity is taking place on the sub-cellular and molecular level.
Interphase. The interphase portion of the cell cycle is relatively long compared to mitosis. Interphase consists of three stages: first gap (G1), synthesis (S) and second gap (G2). The cell replicates DNA only in the S phase. Before the cell can transition from G1 to S, it must clear the G1 checkpoint.
