How many types of DNA polymerases are present in bacteria?

Options

A. Five
B. Three
C. Two
D. One

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the types of DNA polymerases present in bacteria.

2. **Identifying the Types of DNA Polymerases**: In bacteria, there are three main types of DNA polymerases:
- **DNA Polymerase I**
- **DNA Polymerase II**
- **DNA Polymerase III**

3. **Function of Each Polymerase**:
- **DNA Polymerase I**: Primarily involved in DNA repair and also plays a role in removing RNA primers during DNA replication.
- **DNA Polymerase II**: Also involved in DNA repair processes.
- **DNA Polymerase III**: The main enzyme responsible for DNA synthesis during replication.

4. **Conclusion**: Therefore, the total number of DNA polymerases present in bacteria is three.

5. **Final Answer**: The answer to the question is that there are **three types of DNA polymerases** in bacteria.
