Question

The _____ is critical in the cell cycle because it indicates the cell is ready for division. G0 phase G1 phase G2 phase S phase

Answer 1

S phase.

Step-by-step explanation:

During this phase, the DNA within the cell is also copied during this process.

Answer 2

S- phase

Step-by-step explanation:

Cell cycle is divided into two phases: interphase (G1, S and G2 phases) and M phase. M phase is the phase of actual cell division while interphase is the preparatory phase. The S phase of interphase is marked by DNA replication. Error free completion of DNA replication designates the cell to enter the M phase. Any error in DNA replication during S phase is detected by check point and the cell is prevented from M phase.
