What are the three phases of interphase?

The three phases of interphase are G1 (Gap 1), S (Synthesis), and G2 (Gap 2). During G1, the cell grows and prepares for DNA replication, as well as gathers the necessary nutrients and organelles for the upcoming phases. The S phase is when the actual DNA replication occurs, resulting in the formation of two sister chromatids for each chromosome. Following the S phase, G2 serves as a checkpoint where the cell continues to grow and assesses whether it is ready to undergo mitosis.

The correct answer highlights these three critical phases that occur before a cell enters mitosis, while the other options include phases that are not part of interphase or mislabel the components involved in cell division. Understanding these phases is essential for grasping the overall cell cycle and how cells prepare for division and growth.
