Verified step by step guidance

Understand the cell cycle: The cell cycle is divided into several phases, including G1, S, G2, and M phases. Each phase has specific functions and characteristics.

Identify the M phase: The M phase, or mitosis, is the phase where the cell divides into two daughter cells. It follows the preparatory phases where the cell grows and duplicates its DNA.

Review the G2 phase: The G2 phase is the second gap phase where the cell continues to grow and prepares for mitosis. It follows the S phase, where DNA replication occurs.

Determine the sequence of phases: The sequence of the cell cycle is G1 -> S -> G2 -> M. Therefore, the phase immediately before the M phase is the G2 phase.

Consider the other options: G0 phase is a resting phase outside the cycle, G1 phase is the first gap phase, and S phase is where DNA synthesis occurs. These do not immediately precede the M phase.
