27. Which of the following statements best describes the termination of transcription in prokaryotes?
(A) RNA polymerase transcribes through the polyadenylation signal, causing proteins to associate with the transcript and cut it free from the polymerase.
(B) RNA polymerase transcribes through the terminator sequence, causing the polymerase to separate from the DNA and release the transcript.
(C) Once transcription has initiated, RNA polymerase transcribes until it reaches the end of the chromosome.
(D) RNA polymerase transcribes through a stop codon, causing the polymerase to stop advancing through the gene and release the mRNA.
