What happens during the G1 Phase of the cell cycle?

During the G1 Phase of the cell cycle, cell growth occurs as it prepares for DNA replication and subsequent phases. This phase involves the cell increasing in size, synthesizing RNA, and producing proteins that are necessary for DNA synthesis and other cellular functions. Metabolic activity is high, and the cell is actively conducting its normal functions while also preparing the necessary components for duplication.

The G1 Phase sets the stage for the S phase, where DNA replication takes place, but it is important to note that DNA is not replicated during G1. Instead, the cell focuses on growth and the accumulation of the resources required for the next steps in the cycle. Additionally, this phase ensures that the cell is ready to proceed to the next phase by passing critical checkpoints that assess the cell's size and the integrity of its DNA. Other options refer to activities that occur during different phases of the cell cycle, not during G1.
