Which statement is TRUE regarding transcription in bacteria, according to the provided information?

  • A: Bacterial RNA transcripts immediately undergo extensive processing to become usable mRNA.
  • B: Transcription initiation in bacteria involves numerous transcription factors binding sequentially to the promoter before RNA polymerase.
  • C: Termination of transcription in bacteria is identical in detail to that in eukaryotes.
  • D: RNA polymerase in bacteria directly recognizes and binds to the promoter region to initiate transcription.

Explanation

Figure 17.8 and its accompanying text, especially when contrasted with Figure 17.9, indicate that bacterial transcription initiation involves a direct binding of RNA polymerase to the promoter. The text also mentions that bacterial RNA transcripts are immediately usable, and termination details differ from eukaryotes.
