Genetic code shows degeneracy i.e. occurrence of more than 1 codon per amino acid. All the amino acid except methionine and tryptophan are coded by more than 1 codon. For example, valine is specified by GUU, GUC, GUA, GUG This shows that first two bases are common in all the four codons coding for valine. But the third base can be changed.
