I am currently continuing at SunAgri as an R&D engineer. This hairpin plays a central role in the release of the transcript and polymerase at intrinsic termination sites on the DNA template. As the RNA polymerase approaches the end of the gene being transcribed, it hits a region rich in C and G nucleotides. 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. Location of the study area, in the Great Valley Sequence, California, USA. Ns between two sets of Gs represent the nucleotides in the first, second and third loops. "Loops" that are fewer than three bases long are sterically impossible and do not form. This order is determined by the attraction between a codon, a sequence of three nucleotides on the mRNA, and a complementary nucleotide triplet on the tRNA, called an anticodon. Hairpin structure is a pattern that can occur in single-stranded DNA or, more commonly, in RNA. The structure is also known as a stem-loop structure. It occurs when two regions of the same strand, usually complementary in nucleotide sequence when read in opposite directions, base-pair to form a double helix that ends in an unpaired loop. 2022 Nov 15;55(22):3242-3252. doi: 10.1021/acs.accounts.2c00519. In, The effect of hairpin formation in the candidate G4s present in the human gene promoters on the promoter activity. The temporary lapse and weak uracil-adenine bonds cause the hairpin structure to unwind and dissociate from the RNA polymerase, thus terminating transcription. At the end of the replication cycle, these large intermediates of satellite RNA replication are processed down to unit length molecules (circular or linear) before they can be packaged by viruses and carried to other cells for further rounds of replication.[1]. 2021 Nov 18;49(20):12004. doi: 10.1093/nar/gkab1140.
