Enzyme required for transcribing genetic information of DNA into RNA is

Options

A. DNA dependent DNA polymerase
B. DNA dependent RNA polymerase
C. RNA dependent RNA polymerase
D. Both (a) and (b)

Answer

To solve the question regarding the enzyme required for transcribing genetic information of DNA into RNA, we will analyze the options provided and identify the correct enzyme.

### Step-by-Step Solution:

1. **Understanding Transcription**:
- Transcription is the process by which genetic information encoded in DNA is copied into RNA. This process is crucial for gene expression.

2. **Identifying the Enzymes**:
- The options given are:
- A) DNA dependent DNA polymerase
- B) DNA dependent RNA polymerase
- C) RNA dependent RNA polymerase
- D) Both A and B

3. **Analyzing Option A: DNA dependent DNA polymerase**:
- This enzyme uses DNA as a template to synthesize new DNA. It is involved in DNA replication, not transcription.
- **Conclusion**: This option is incorrect for transcription.

4. **Analyzing Option B: DNA dependent RNA polymerase**:
- This enzyme uses DNA as a template to synthesize RNA. It is specifically responsible for the transcription process.
- **Conclusion**: This option is correct for transcription.

5. **Analyzing Option C: RNA dependent RNA polymerase**:
- This enzyme uses RNA as a template to synthesize new RNA. It is involved in processes like RNA replication, not in transcribing DNA to RNA.
- **Conclusion**: This option is incorrect for transcription.

6. **Analyzing Option D: Both A and B**:
- Since option A is incorrect, this option cannot be correct either.
- **Conclusion**: This option is incorrect.

### Final Answer:
The correct enzyme required for transcribing genetic information of DNA into RNA is **DNA dependent RNA polymerase** (Option B).
