Which outcome occurs when RNA polymerase encounters a transcription terminator hairpin loop in DNA template?

💡 Explanation

When RNA polymerase encounters a hairpin loop, Rho-independent termination occurs because, due to the loop's stable structure, polymerase translocation pauses, weakening the DNA-RNA hybrid and causing dissociation. Therefore, transcriptional pausing and dissociation occur effectively stopping mRNA synthesis, rather than proceeding into other processes such as acetylation, splicing, or methylation which depend on other factors.
