Final answer:
Appropriate bacterial transcription requires RNA polymerase, Sigma Factor, Signals within the Promoter region, and Signals within the Terminator region.
Step-by-step explanation:
Appropriate bacterial transcription requires all of the above elements: RNA polymerase, Sigma Factor, Signals within the Promoter region, and Signals within the Terminator region.
In bacteria, a single RNA polymerase transcribes all kinds of RNA. It associates with a Sigma Factor protein to initiate transcription, recognizing different promoter sequences for different genes. Promoter regions contain signals that direct RNA polymerase to the start site, and terminator regions contain signals that help terminate transcription.
Therefore, all of these elements are required for proper bacterial transcription to occur.
