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.

Question

Quizplus · Accepted Answer

In prokaryotes, the termination of transcription is signaled by a terminator sequence, which causes RNA polymerase to separate from the DNA and release the newly synthesized RNA transcript. Option A and E are not applicable to prokaryotes, while option C is describing termination in eukaryotes involving splicing out introns. Option D is also incorrect as prokaryotes do not have chromosomes with distinct ends.
