WebOnce a polymerase meets this loop, it falls of and transcription ends. Another more general example is tRNA, a central player in protein synthesis, which is partially formed by hairpin loops. The tRNA molecule actually contains three hairpin loops that form the shape of a three-leafed clover. WebRNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of …
