You are attempting to determine which step of prokaryotic translation a new antibiotic inhibits.You have determined that the antibiotic interacts with a translational factor but need to identify which one.If the new antibiotic interferes with elongation,which of the following factors could be a potential site of action?
A)IF3 interaction with an aminoacyl tRNA B)EF-Tu placement of N-formylmethionine onto the ribosome C)EF-Tu interaction with an aminoacyl tRNA D)EF-Ts translocation of tRNAs from the A site to the P site E)All of these could be potential sites of action.
