WebNov 20, 2001 · Aminoacyl tRNAs are generated typically through action of the diverse family of aminoacyl-tRNA synthetases (AARSs). One of the hallmarks of these enzymes is the exquisite specificity with which each selects and aminoacylates only its cognate tRNA(s) with only its cognate amino acid (2–5). penske buffalo on broadwayWebThe in vitro reconstruction of life-like self-reproducing systems is a major challenge in in vitro synthetic biology.
