15 maj 2024 · A Stem-loop can be defined as a hairpin-like pattern formed because of the intramolecular base pairing of the nucleotide sequence (especially in palindromic sequence) within the same molecule. Here, the nucleotide pairs within the molecule to form a double helix structure ending in an unpaired loop resulting in a hairpin-like structure.
A hairpin is a special case of a turn, in which the direction of the protein backbone reverses and the flanking secondary structure elements interact. For example, the beta hairpin connects two hydrogen-bonded, antiparallel β-strands.
11 sie 2024 · Beta-hairpin or beta-turn This motif is present in most antiparallel beta structures, both as an isolated ribbon and as part of beta sheets. Figure \(\PageIndex{8}\) shows an interactive iCn3D model of the beta hairpin from bovine pancreatic trypsin inhibitor (1k6u)
A hairpin loop is an unpaired loop of messenger RNA (mRNA) that is created when an mRNA strand folds and forms base pairs with another section of itself.
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.
Abstract. Hairpin molecules have attracted a great deal of interest for many years. On one hand, this is because of their role in cellular processes, the recognition between the codon on mRNA and the anti-codon loop of tRNA being the most outstanding example.
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.
