. Suppose you modify the glycine-tRNA so that the glycine is changed to valine. Based on the results of the Benzer experiments, because the protein synthesis machinery recognizes the . proteins would have valines where glycines normally are; tRNA anticodon proteins would have glycines where valines normally are; amino acid attached to the tRNA nothing should change in proteins; amino acid attached to the tRNA proteins would have valines where glycines normally are; amino acid attached to the tRNA nothing should change in proteins; tRNA anticodon
