WebJan 20, 2012 · A mechanism for specific aminoacylation of RNA hairpins and ancestral tRNA With an RNA world at acidic pH, a possible mechanism for the specific aminoacylation of tRNA (and its hairpin precursor [ 19, 20 ]) can be suggested. WebDec 3, 2015 · Many studies suggest that the contemporary full-length tRNA was formed by the ligation of half-sized hairpin-like RNAs. A minihelix (a coaxial stack of the acceptor stem on the T-stem of tRNA) can function both in aminoacylation by aminoacyl tRNA synthetases and in peptide bond formation on the ribosome, indicating that it may be a vestige of ...

WebSep 5, 2024 · DNA hairpin ligation is highly selective Without a selective adapter ligation to the tRNA 3ʹ-end, it is essential to efficiently separate tRNAs from other RNAs in the preparation, as these would be unavoidably included in the analysis. WebApr 10, 2024 · Transfer RNA or tRNA is a short RNA molecule with the function of assisting in the protein synthesis in a cell. It has two important sections, a region that attaches with particular amino acid and a trinucleotide which is commonly called an anticodon.
