Cell cycle is primarily divided into Interphase and M phase. Interphase is further divided into four stages- G₀, G1, S, and G2.
G₀ 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.
