G1 phase

The G1 phase is the initial stage of a cell's life cycle where it grows larger, produces the necessary proteins, and prepares for DNA replication. Think of it as the cell's "growth and readiness" period, during which it assesses whether conditions are favorable for division. This phase ensures the cell has enough resources and health to duplicate its DNA accurately in the next stage. G1 is essential for maintaining proper cell function and for tissue growth and repair in the body.
