Explanation:
Detailed explanation-1: -Methionine and tryptophan are the only two amino acids that are coded for by just a single codon (AUG and UGG, respectively). The other 18 amino acids are coded for by two to six codons. Because most of the 20 amino acids are coded for by more than one codon, the code is called degenerate.
Detailed explanation-2: -This rescue effect provided compelling evidence that the genetic code for one amino acid is indeed a three-base, or triplet, code.
Detailed explanation-3: -The number of bases required for coding in an amino acid is three. One amino acid is formed by three base pairs. AUG is the triplet of bases that codes for methionine.
