What role does G1 play in the cell cycle and how does it contribute to the overall process of cell division?

During the G1 phase of the cell cycle, the cell grows and carries out its normal functions. It is a crucial phase where the cell prepares for DNA replication in the subsequent S phase. G1 also serves as a checkpoint to ensure that the cell is ready to proceed to the next phase of the cell cycle. Overall, G1 plays a key role in regulating cell division by ensuring that the cell is healthy and ready to replicate its DNA.
