Interphase includes which of the following?

G1 only

S only

G2 only

G1, S, and G2

Interphase is the stage of the cell cycle when the cell grows, duplicates its DNA, and prepares for division. During G1, the cell increases in size and carries out normal functions. The S phase is when DNA replication occurs, so each chromosome is copied to form sister chromatids. In G2, the cell grows a bit more and prepares structures needed for mitosis, ensuring everything is ready for chromosome separation. Because interphase comprises all three subphases—G1, S, and G2—it includes the entire sequence of growth, DNA replication, and preparation before mitosis. (G0 is a resting state outside this cycle, and mitosis comes after interphase.)
