Hairpin structure formation
WebJan 7, 2024 · This study presents an adenosine (A)-based molecular beacon (MB) for selective detection of Naja atra cardiotoxin (CTX) that functions by utilizing the competitive binding between CTX and the poly(A) stem of MB to coralyne. The 5′- and 3′-end of MB were labeled with a reporter fluorophore and a non-fluorescent quencher, respectively. … WebA 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 the same strand. The resulting structure looks like a loop or a U-shape. Hairpins are a common type of secondary structure in RNA molecules.

WebSep 5, 2024 · Image 5: Depiction of cross dimer and hairpin formation. For both parameters (self-complementarity and self 3′-complementarity), the lower the number, the better. However, secondary structures can be avoided by adjusting the annealing temperature (in most cases, an increase in temperature), avoiding cross homology, and … WebThe results indicate that for DNA the optimal loop consists of four or five residues. The observation that hairpins are formed for n less than 3 and that the stability of DNA hairpins is at its maximum for loop lengths of four to five residues is at variance with earlier findings for RNA. In the latter case the optimal loop size consists of six ...
