Overview of the role of tRNA in protein synthesis (a) Aminoacyl-tRNA synthetases catalyze the attachment of amino acids to their cognate tRNAs to result in “charged” aminoacyl-tRNAs; (b) Each tRNA has a specific sequence that corresponds to an amino acid. Multiple isoaccepting tRNAs may specify a single amino acid; (c) Nascent peptides are synthesized at the ribosome using the mRNA template. Charged tRNAs with their corresponding amino acids are delivered to the ribosome, one by one, by matching anticodons to mRNA codons to result in a protein.
