Which of the Following Statements Best Describes the Termination of Transcription

question 75

Multiple Choice

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) RNA polymerase transcribes through an intron, and the snRNPs cause the polymerase to let go of the transcript.
• D) Once transcription has initiated, RNA polymerase transcribes until it reaches the end of the chromosome.
• E) RNA polymerase transcribes through a stop codon, causing the polymerase to stop advancing through the gene and release the mRNA.
