In both of Henry's mutations, it is the first nucleotide in the DNA triplet code that has been changed. a. Using the genetic code chart below, create a list of single nucleotide changes in the two affected triplet codes described for Henry's genes that could occur WITHOUT resulting in a change in the amino acid in the enzyme. NOTE: The code chart below contains mRNA codons and the amino acids associated with those codons. Your list should contain DNA triplet codes. b. How many triplet code changes did you find that could occur WITHOUT resulting in an amino acid change in the enzyme
