Which one of the following enzyme is responsible for the synthesis of DNA from RNA

Options

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

Answer

To solve the question "Which one of the following enzyme is responsible for the synthesis of DNA from RNA?", we will analyze the options provided and identify the correct enzyme.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for an enzyme that synthesizes DNA from RNA. This process is known as reverse transcription.

2. **Identify the Options**: The options given are:
- DNA polymerase
- RNA polymerase
- Reverse transcriptase
- DNA ligase

3. **Analyze Each Option**:
- **DNA polymerase**: This enzyme synthesizes DNA from a DNA template, not from RNA.
- **RNA polymerase**: This enzyme synthesizes RNA from a DNA template, not the other way around.
- **Reverse transcriptase**: This enzyme synthesizes complementary DNA (cDNA) from an RNA template. This is the process of reverse transcription.
- **DNA ligase**: This enzyme is involved in joining DNA fragments together but does not synthesize DNA from RNA.

4. **Conclusion**: The only enzyme that synthesizes DNA from RNA is **reverse transcriptase**. Therefore, the correct answer is option **reverse transcriptase**.

### Final Answer:
The enzyme responsible for the synthesis of DNA from RNA is **reverse transcriptase**.
