Verified step by step guidance

Understand the cell cycle: The cell cycle consists of several phases that a cell goes through to divide and produce new cells. These phases include G1, S, G2, and M phases.
Identify the purpose of each phase: G1 phase is the first gap phase where the cell grows and carries out normal functions. S phase is where DNA replication occurs. G2 phase is the second gap phase where the cell prepares for mitosis. M phase is where mitosis and cytokinesis occur.
Focus on the G2 phase: During the G2 phase, the cell continues to grow and produces proteins and organelles. It also checks for DNA damage and ensures all DNA is replicated correctly before proceeding to mitosis.
Recognize the role of checkpoints: The G2 phase includes a critical checkpoint to ensure that the cell is ready to enter mitosis. This involves checking the integrity of the DNA and the completion of DNA replication.
Conclude that the G2 phase is the preparation phase for mitosis: Based on the functions and checkpoints in the G2 phase, it is clear that this is the phase where the cell prepares for the process of mitosis.
