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.
G1: Cells can exit the cell cycle and enter G0 or be committed to initiate DNA synthesis late in G1. T/F : The longest stage of interphase is G2. False: The longest stage of interphase is S; cells typically spend about 7 hours in this stage. The shortest stage of interphase is G2 (3 hours), although the shortest stage of the entire cell cycle is mitosis (1 hour).
