A21. Two single-base substitutions in the trpA gene of E.coli both affected amino acid number 234. In one mutant, the amino acid at this position was now Cys; in the other mutant it was Asp. What was the most likely amino acid encoded at position 234 in the wild type protein? E. Pro A. Val B. Trp D. Arg C. Gly
