Verified step by step guidance

Understand the cell cycle: The cell cycle consists of several phases, including G1, S, G2, and M phases. Each phase has specific functions and processes.

Identify the G1 phase: During the G1 phase, the cell grows in size and synthesizes various enzymes and nutrients that are required for DNA replication and cell division. This phase is crucial for preparing the cell for the subsequent S phase.

Recognize the S phase: Although not directly asked, it's important to note that DNA replication occurs during the S phase, which follows the G1 phase.

Identify 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, preparing the cell for mitosis.

Conclude the role of G1 and G2: Both G1 and G2 phases are primarily involved in cell growth and preparation for mitosis, ensuring the cell is ready to divide during the M phase.
