Recognition sequence for transcription in prokaryotes is
(a) TATATAT
(b) TATAAT
(c) TATAAAT
(d) CAAT

Options

A. TATATAT
B. TATAAT
C. TATAAAT
D. CAAT

Answer

To solve the question regarding the recognition sequence for transcription in prokaryotes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: The question asks for the recognition sequence for transcription in prokaryotes. In prokaryotes, transcription is initiated at specific DNA sequences.

2. **Identify the Key Term**: The key term here is "Pribnow box," which is a well-known consensus sequence found in prokaryotic promoters.

3. **Recall the Consensus Sequence**: The consensus sequence for the Pribnow box is typically recognized as "TATAAT." This sequence is crucial for the binding of RNA polymerase during the initiation of transcription.

4. **Evaluate the Options**:
- (a) TATATAT - This is not the correct sequence.
- (b) TATAAT - This matches the known Pribnow box consensus sequence.
- (c) TATAAAT - This does not match the consensus sequence.
- (d) CAAT - This is also not the correct sequence.

5. **Select the Correct Answer**: Based on the evaluation, the correct recognition sequence for transcription in prokaryotes is **(b) TATAAT**.

### Final Answer:
The recognition sequence for transcription in prokaryotes is **(b) TATAAT**.
