Keeping in mind the known nature of the genetic code, the information given about phage MS2 in Problem
13.32, and the information you have learned about nitrous acid in Problem 13.35, would you expect nitrous acid to induce any mutations that would result in amino acid substitutions of the type glycine → another amino acid if the mutagenesis were carried out on a suspension of mature (nonreplicating) MS2 bacteriophage?
If so, by what mechanism? If not, why not?
