Understand that the cell cycle consists of interphase and the mitotic phase. Interphase is further divided into G1, S, and G2 phases.
Recognize that interphase is the period of the cell cycle during which the cell grows and DNA is replicated.
Identify that the G1 phase is the first stage of interphase, where the cell grows and carries out normal functions.
Note that the S phase is the second stage of interphase, where DNA replication occurs.
Acknowledge that the G2 phase is the final stage of interphase, where the cell prepares for mitosis. Interphase, as a whole, is the longest phase of the cell cycle.
