WebQuestion: uestion7 Which of the following is NOT true of the formation of a bacterial translation initiation complex? O A) The 30S ribosome associates with the mRNA before the 50S ribosome. O B) N-formylmethionine-tRNAfimet binds in the P site IF-3 binding to GTP is required for the charged tRNA to associate with the first mRNA codon. Elongation of the polypeptide chain involves addition of amino acids to the carboxyl end of the growing chain. The growing protein exits the ribosome through the polypeptide exit tunnel in the large subunit. Elongation starts when the fMet-tRNA enters the P site, causing a conformational change which opens the A site for the new aminoacyl-tRNA to bind. This binding is facilitated by elongation fact…
