Step 1: Understand the process of bacterial transcription.
- Rho factor: Involved in the termination of transcription in bacteria.
- Sigma factor: Involved in the initiation of transcription in bacteria by binding RNA polymerase to the promoter.
- DNA dependent RNA polymerase: The enzyme responsible for synthesizing RNA during transcription.
Step 2: Identify the factor not involved in transcription.
- Methyl guanosine triphosphate: This is involved in the capping of mRNA in eukaryotes, not in bacterial transcription.
Conclusion:
The correct answer is (2) Methyl guanosine triphosphate.
Final Answer:
\[
\boxed{\text{The correct answer is Methyl guanosine triphosphate.}}
