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.

Question

Quizplus · Accepted Answer

In prokaryotes, transcription termination is signaled by a terminator sequence on the DNA template strand. When RNA polymerase transcribes through this sequence, it destabilizes the RNA-DNA hybrid and causes the polymerase to dissociate from the DNA and release the newly synthesized RNA transcript.
