The cell cycle is divided into two basic phases: Interphase and M Phase (Mitosis). Interphase is further subdivided into three phases in the following order: G1 phase (Gap 1), S phase (Synthesis), and G2 phase (Gap 2). The M Phase follows the G2 phase. Therefore, the correct sequence of phases in the cell cycle is G1 → S → G2 → M , , .
