Verified step by step guidance1
Understand the cell cycle: The cell cycle consists of interphase (G1, S, and G2 phases) and the mitotic phase (M phase).
Identify the phase where DNA replication occurs: DNA replication takes place during the S phase (Synthesis phase).
Determine what happens after DNA replication: After the S phase, the cell enters the G2 phase.
Recognize the purpose of the G2 phase: During the G2 phase, the cell continues to grow and prepares for mitosis by producing proteins and organelles.
Conclude the sequence: The G2 phase occurs after the S phase and before the M phase, which is the start of mitosis.
