What event occurs in G1?

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

A check that growth factors are present

A check that the cell is large enough for division

A check that nutrients are sufficient

Answer 5

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.

Answer 6

cell growth and new proteins
