What is correct for bacterial transcription?

Options

A. mRNA requires processing to become active
B. Translation can begin when mRNA is fully transcribed
C. Transcription and translation takes place in the same compartment
D. Rho factor initiates the process

Answer

To determine what is correct for bacterial transcription, we will analyze each of the provided statements one by one.

### Step-by-Step Solution:

1. **Evaluate the first statement: "mRNA requires processing to become active."**
- In eukaryotes, mRNA undergoes processing (capping, polyadenylation, and splicing) before it can be translated. However, in bacteria, mRNA does not require such processing. It is transcribed and can be translated directly.
- **Conclusion**: This statement is **incorrect** for bacterial transcription.

2. **Evaluate the second statement: "Translation can begin when mRNA is fully transcribed."**
- In bacteria, transcription and translation can occur simultaneously. This means that ribosomes can start translating the mRNA even before the entire mRNA molecule has been synthesized.
- **Conclusion**: This statement is **incorrect** for bacterial transcription.

3. **Evaluate the third statement: "Transcription and translation take place in the same compartment."**
- In bacteria, both transcription and translation occur in the cytoplasm, as there is no nucleus to separate these processes. Therefore, they do indeed take place in the same compartment.
- **Conclusion**: This statement is **correct** for bacterial transcription.

4. **Evaluate the fourth statement: "Rho factor initiates the process."**
- The Rho factor is involved in the termination of transcription in bacteria, not in the initiation. The initiation of transcription is primarily facilitated by the sigma factor, which helps RNA polymerase bind to the promoter region of the DNA.
- **Conclusion**: This statement is **incorrect** for bacterial transcription.

### Final Answer:
The correct statement regarding bacterial transcription is: **"Transcription and translation take place in the same compartment."**
