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 from DNA into RNA, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Process of Transcription**:
- Transcription is the process by which genetic information from DNA is copied into RNA. This process is crucial for gene expression.

2. **Identify the Enzymes Involved**:
- There are specific enzymes that facilitate the transcription process. The primary enzyme responsible for this is RNA polymerase.

3. **Analyze the Options Given**:
- The question provides several options, and we need to evaluate each one to determine which enzyme is responsible for the transcription of DNA into RNA.

4. **Evaluate Each Option**:
- **Option A: DNA dependent DNA polymerase**:
- This enzyme synthesizes DNA from a DNA template. It is not involved in transcription, so this option is incorrect.

- **Option B: DNA dependent RNA polymerase**:
- This enzyme synthesizes RNA from a DNA template, making it essential for transcription. This is the correct answer.

- **Option C: RNA dependent RNA polymerase**:
- This enzyme synthesizes RNA from an RNA template, which is not relevant to the transcription of DNA into RNA. Thus, this option is incorrect.

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

5. **Conclusion**:
- After evaluating all the options, the correct answer is **Option B: DNA dependent RNA polymerase**.

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