Cell cycle is primarily divided into Interphase and M phase. Interphase is further divided into four stages- Gā, G1, S, and G2.
Gā is the state of rest. In this stage, cell quits dividing or comes out of the process of cell division. In other words, it ceases to divide.
G1 ( gap 1) phase is the phase of interphase in which cell grows and conducts its metabolic functions. It synthesizes essential proteins required for the next phase, which is S phase.
S phase follows G1. During S ( synthesis) phase, DNA is duplicated. Thus, to produce two identical daughter cells, replication of DNA takes place in this phase. G2 phase follows this phase.
In G2 ( gap 2) phase, cell produces new proteins and continues to grow. It prepares for the M phase. Chromosomes start coiling and condensation takes place.
Thus, the correct match for the stages of interphase is-
1. G1 phase- The cell is conducting its metabolic functions.
2. S phase- DNA material is being duplicated.
3. G0 phase- The cell ceases to divide.
4. G2 phase- Cells prepare for M phase, and the chromosomes begin to coil and condense.
