During replication of a bacterial chromosome DNA syntnthesis stars from a replication origin site and

Options

A. RNA primer are involved
B. is facilitated by telomerase
C. moves in one direction of the site
D. moves in bi- directional way

Explanation

**Step-by-Step Solution:**

1. **Understanding the Context**: The question is about the replication of bacterial chromosomes. Bacteria are prokaryotic organisms, and their DNA replication process has specific characteristics.

2. **Identifying the Origin of Replication**: In bacterial DNA replication, the process begins at a specific location known as the origin of replication (often abbreviated as ORI). This is the site where the DNA unwinds and replication starts.

3. **Direction of Replication**: DNA synthesis in bacteria occurs in a bidirectional manner. This means that once the replication process starts at the origin, the replication forks move away from the origin in both directions along the circular bacterial chromosome.

4. **Key Terms**:
- **Replicon**: The unit of replication in bacteria is referred to as a replicon. This includes the origin of replication and the DNA that is replicated from that point.
- **Bidirectional Replication**: This term indicates that replication occurs simultaneously in two opposite directions from the origin.

5. **Conclusion**: The correct answer to the question is that during bacterial chromosome replication, the DNA synthesis moves in a bidirectional way.

**Final Answer**: Moves in a bidirectional way.
