Understand the overall structure of the eukaryotic cell cycle, which consists of Interphase (G1, S, G2 phases) and M phase (mitosis and cytokinesis).
Recall that Interphase is the period when the cell grows, duplicates its DNA, and prepares for mitosis, while M phase is the process of cell division itself.
Recognize that within Interphase, G1 is the growth phase, S is the DNA synthesis phase, and G2 is the preparation for mitosis.
Compare the duration of each phase: Interphase generally takes much longer than M phase because the cell spends most of its time growing and replicating DNA.
Conclude that Interphase (G1, S, and G2 combined) typically occupies the longest portion of a cell's life under normal growth conditions.
