Question

The transcription terminator stops DNA polymerase, AND results in the polymerase falling off the DNA template. adds a terminator nucleotide to the RNA, AND results in a hairpin loop structure in RNA. stops DNA polymerase, AND adds a terminator nucleotide to the RNA. results in a hairpin loop structure in RNA, AND stops DNA polymerase. results in a hairpin loop structure in RNA, AND results in the polymerase falling off the DNA template.

Answer 1

Answer:

Results in a hairpin loop structure in RNA, AND results in the polymerase falling off the DNA template.

Explanation:

As the RNA polymerase arrives at the terminator site, it pauses. The termination of RNA transcription occurs when an RNA transcript with a self-complementary sequence is formed leading to the formation of the hairpin structure. The hairpin structure has 15-20 nucleotides.  

The hairpin structure of RNA weakens A=U base pairs in RNA-DNA hybrid and/or weakens the interaction between RNA and RNA polymerase. The overall effect is the dissociation of RNA polymerase from the complex and termination of the transcription.
