DNA-Gyrase enzyme, that participates in the process of DNA-replication is a type of :-

Options

A. DNA ligase
B. DNA topoisomerase
C. Reverse transcriptase
D. DNA polymerase

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the type of enzyme that DNA-Gyrase is, specifically in the context of its role in DNA replication.

2. **Identifying DNA-Gyrase**: DNA-Gyrase is an enzyme that is crucial during the process of DNA replication. It helps manage the supercoiling that occurs ahead of the replication fork.

3. **Classifying DNA-Gyrase**: DNA-Gyrase is classified as a type of topoisomerase. Topoisomerases are enzymes that alter the supercoiling of DNA. They can introduce or remove twists in the DNA helix, which is essential for the replication process.

4. **Differentiating from Other Enzymes**: The question provides other options:
- DNA ligase, which is responsible for sealing nicks in the DNA.
- Reverse transcriptase, which synthesizes DNA from an RNA template.
- DNA polymerase, which synthesizes new DNA strands during replication.

5. **Conclusion**: Based on the classification and function of DNA-Gyrase, the correct answer is that DNA-Gyrase is a type of topoisomerase.

**Final Answer**: DNA-Gyrase is a type of topoisomerase.
