The cell cycle comprises of several phases: G0, G1, S, G2, and M. At all phases, there are checkpoints to regulate cell proliferation. G0 is the resting phase. G1 and G2 are gap phases before mitosis. In G1, amino-acids and enzymes required for DNA replication are mobilized. At the G2 checkpoint, the cellâ??s readiness for mitosis is confirmed.

In the G1 phase of the cell cycle, the cell grows in size and undergoes normal metabolic activities to prepare for DNA replication in the following S phase. It is a critical checkpoint where the cell checks for any damage or irregularities before proceeding to the next phase of the cycle.
G0: is the phase in wich the cell rest and quit dividing by a short or long period.
G1: in this phase the cell starts to grow in size.
G2: in this phase the cell grows, prepare and synthesis proteins that are required on the M phase of cell cycle.
A check that growth factors are present
A check that the cell is large enough for division
A check that nutrients are sufficient
During the G1 phase the cell grows. There is a checkpoint the in the G1 phase. The cell can either pass the checkpoint and enter the S phase or the G0 phase.
G1 phase is when cell growth occurs
The restriction point occurs during the G1 phase of the cell cycle. It is a point at which the cell commits to entering the S phase and proceeding with DNA replication.
In Ontario, Canada, the date changes for G1 drivers once they pass their G1 road test and move on to become a G2 driver. This transition typically occurs after 12 months of holding a G1 license, or 8 months with completion of an approved driver education course.
No, G1 and S phases are distinct from one another. In G1 the cell does normal metabolic processes, its differentiated cell-type specific functions, cell growth, duplication of cytoplasmic components (other than genetic material), and synthesizes proteins required for duplication of genetic material. S phase is the point in the cell cycle when chromosomal duplication occurs. Hope that helps!
Phosphate is not a period of time during which an event can occur.
