What is the role of tRNA in translation?

The key idea is that tRNA acts as the adaptor that translates the mRNA codon sequence into a specific amino acid. Each tRNA is charged with one amino acid, then its anticodon pairs with the corresponding codon on the mRNA inside the ribosome. This pairing ensures the correct amino acid is added to the growing polypeptide chain. The ribosome catalyzes the peptide bond formation between the amino acid on the tRNA in the A site and the one on the tRNA in the P site, while aminoacyl-tRNA synthetases ensure each tRNA is carrying the correct amino acid. In this system, mRNA provides the sequence information, not the amino acids, and rRNA forms the ribosome and facilitates catalysis.
