Enlist the peculiar events which occur during Sphase and `G_(2)`.-phase of interphase.

Explanation

### Step-by-Step Solution

1. **Understanding Interphase**:
- Interphase is the longest stage of the cell cycle in eukaryotic cells. It is a preparatory phase where the cell prepares for division.

2. **Events during S Phase (Synthesis Phase)**:
- **DNA Replication**: The primary event in the S phase is the replication of DNA. Each chromosome is duplicated, resulting in two sister chromatids for each chromosome.
- **Histone Protein Synthesis**: Along with DNA replication, histone proteins are synthesized. These proteins are crucial for packaging DNA into the chromatin structure, allowing it to fit within the nucleus.
