What are the stages of Interphase?

Interphase consists of three distinct stages: G1, S, and G2. During G1 (Gap 1), the cell grows and carries out normal metabolic functions, preparing for DNA synthesis. The S phase (Synthesis) is where DNA replication occurs, resulting in two sets of chromosomes. Following the S phase is G2 (Gap 2), where the cell continues to grow and prepares for mitosis, ensuring all components are ready for cell division.

In contrast, the G0 stage mentioned in another choice refers to a resting state where cells are not actively preparing to divide. While some cells may enter this phase, it is not officially considered a part of the interphase sequence.

The option indicating no stages in interphase is incorrect because interphase is a crucial part of the cell cycle, comprising significant preparatory phases for division.

Finally, the stages mentioned in another choice—prophase, metaphase, and anaphase—are associated with mitosis (the process of cell division), not interphase, which takes place before mitosis begins. Therefore, the correct option identifies the true stages of interphase through its systematic progression of cell preparation for division.
