tRNAs interpret the genetic code. Each binds both to a codon (in mRNA) by base- pairing and to an aa. Anticodon in tRNA binds codon. anticodon amino acid attachment site

There are MANY tRNAs. Each binds to the right codon and the right amino acid. An Aminoacyl-tRNA synthetase binds BOTH to a specific aa and a specific tRNA and covalently links them using energy from ATP hydrolysis.
