Any double-stranded region of single-stranded deoxyribonucleic acid or ribonucleic acid formed by base-pairing between complementary base sequences on the same strand. Epub 2016 Nov 30. Hairpin loops, if present can greatly reduce the efficiency of the reaction by limiting its availability and ability to bind to the target site. Intrinsic termination of transcription in Escherichia coli involves the formation of an RNA hairpin in the nascent RNA. The hairpin loop forms in an mRNA strand during transcription and causes the RNA polymerase to become dissociated from the DNA template strand. This process is known as rho-independent or intrinsic termination, and the sequences involved are called terminator sequences. J. Frasson I, Pirota V, Richter SN, Doria F. Int J Biol Macromol.
