Differentiate betwen `G_(1)`, and `G_(2)`, subphases of interphase. OR Discuss the significance of mitosis.

Explanation

### Step-by-Step Solution

**1. Definition of Interphase:**
- Interphase is the longest phase of the cell cycle, during which the cell grows, performs its normal functions, and prepares for division. It consists of three sub-phases: G1, S, and G2.

**2. G1 Phase (Gap 1):**
- The G1 phase occurs immediately after cell division (mitosis) and before DNA replication.
- During G1, the cell undergoes significant growth, synthesizing RNA and proteins necessary for DNA replication.
