What is the site of DNA replicaiton in cell cycle?

Answer

### Step-by-Step Solution:

1. **Understanding the Cell Cycle**: The cell cycle is a series of events that cells go through as they grow and divide. It consists of two main phases: Interphase and M phase (Mitotic phase).

2. **Dividing Interphase**: Interphase is further divided into three sub-phases:
- **G1 Phase (Gap 1)**: This is the first phase where the cell grows and synthesizes proteins and RNA.
- **S Phase (Synthesis)**: This is the crucial phase where DNA replication occurs.
- **G2 Phase (Gap 2)**: In this phase, the cell continues to grow and prepares for mitosis.

3. **Identifying the Site of DNA Replication**: The specific site of DNA replication in the cell cycle is during the S phase. This is where the cell synthesizes a complete copy of the DNA in its nucleus.

4. **M Phase Overview**: The M phase follows interphase and is where the cell divides. It includes several stages: prophase, metaphase, anaphase, and telophase. However, DNA replication does not occur during this phase.

5. **Conclusion**: Therefore, the site of DNA replication in the cell cycle is the S phase of interphase.

### Final Answer:
The site of DNA replication in the cell cycle is the S phase of interphase.
