WebThe ribosome has three binding sites for tRNAs: E (exit), P (peptide), and A (acceptor). Once tRNAs have given up their amino acids and are uncharged, they leave the ribosome through the E site. The A site accepts incoming charged tRNAs and the growing polypeptide chain resides in the P site. The initiator tRNA begins in the P site.
