Webribosome Four binding sites are located on the ribosome, one for mRNA and three for tRNA. The three tRNA sites are labeled P, A, and E. The P site, called the peptidyl site, binds to the tRNA holding the growing polypeptide chain of amino acids. Which binding site on the ribosome does the recruited tRNA bind to first? WebAssembly of the subunits on the mRNA forms three tRNA binding sites. B. During translation, charged tRNAs enter the Acceptor site, and the anticodon on the tRNA base pairs with the codon in the mRNA.
