A Fictional Antibiotic. In a study involving a cell-free protein synthesizing system from E. coli, the polyribonucleotide AUGUUUUUUUUUUUU directs the synthesis of the oligopeptide fMet-Phe-Phe-Phe-Phe. In the presence of Rambomycin, a new antibiotic just developed by Macho Pharmaceuticals, only the dipeptide fMet-Phe is made.
(a)What step in polypeptide synthesis does Rambomycin inhibit Explain your answer.
(b)Will the oligopeptide product be found attached to tRNA at the end of the uninhibited reaction Will the dipeptide product be found attached to tRNA at the end of the Rambomycin-inhibited reaction Explain.
