"WebHairpin 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.

Hairpin loop

Beta hairpins were originally categorized solely by the number of amino acid residues in their loop sequences, such that they were named one-residue, two-residue, etc. This system, however, is somewhat ambiguous as it does not take into account whether the residues that signal the end of the hairpin are singly or doubly hydrogen bonded to one another. An improved means of classification has since been proposed by Milner-White and Poet. Beta hairpins are broken into … WebJan 19, 1993 · A computational procedure for generating conformations of DNA hairpin loop structures from a broad range of low-energy starting states is described. The starting point of the modeling is the distribution of oligonucleotide chain conformations obtained from Monte Carlo simulations of feasible dinucleotide steps.
