Meaning and Definition
The first gap phase in the cell cycle, following mitosis and preceding DNA synthesis, where the cell grows and prepares for DNA replication.
In cell biology, the period of cell growth and normal metabolic activity before replicating its DNA. Cells may also exit the cycle into a resting state (G0) from this phase.
