Hairpin rna structure

WebDNA and RNA hairpins participate in many critical rate-limiting biochemical processes [1,2,3,4,5].These sequences are often chaperoned by ligands that facilitate the formation of a diverse set of secondary and tertiary structures to suit their roles [2,3,4,5,6,7,8].The transactivation response (TAR) sequence in the HIV-1 virion forms a hairpin, which is … Stem-loops occur in pre-microRNA structures and most famously in transfer RNA, which contain three true stem-loops and one stem that meet in a cloverleaf pattern. The anticodon that recognizes a codon during the translation process is located on one of the unpaired loops in the tRNA. Two nested stem-loop structures occur in RNA pseudoknots, where the loop of one structure forms part of the second stem.
