how long is interphase related to the cell cycle
The duration of time spent in interphase and in each stage of interphase is variable and depends on both the type of cell and the species of organism it belongs to. Most cells of adult mammals spend about 20 hours in interphase; this accounts for about 90% of the total time involved in cell division.Interphase includes G1, S, and G2 phases. Mitosis and cytokinesis, however, are separate from interphase. G2 (Gap 2), in which the cell resumes its growth in preparation for division. 2  In addition, some cells that do not divide often or ever, enter a stage called G0 (Gap zero), which is either a stage separate from interphase or an extended G1.
