The anticodon of a tRNA pairs completely with the mRNA codon in both the A site and the P site of the ribosome. The A site is where the aminoacyl-tRNA enters and the codon-anticodon pairing occurs, while the P site is where the peptidyl-tRNA is located, carrying the growing polypeptide chain. The E site is where the deacylated tRNA exits the ribosome.
