WebIn bacteria, archaea, and eukaryotes, the intact ribosome has three binding sites that accomodate tRNAs: The A site, the P site, and the E site. Incoming aminoacy-tRNAs (a tRNA with an amino acid covalently attached is called an aminoacyl-tRNA) enter the ribosome at the A site. WebAug 14, 2024 · After peptide bond formation, the tRNA binds briefly to the E site before leaving the ribosome. Additionally, the rRNA has a site for binding to the ribosomal proteins, and it analyses and distinguishes the residues of RNA from proteins.
