A hairpin loop is an unpaired loop of messenger RNA that is created when an mRNA strand folds and forms base pair with another section of the same strand . Intrinsic termination of transcription in E.coli involves a formation of an RNA hairpin in the nascent RNA . The hairpin plays a central role in relase of transcript and polymerase at intrinsic termination site on the DNA template. So that turns are formed from complimentary base pairing and cause separation of the RNA transcript and RNA polymerase.
