A codon that specifies leucine undergoes a single-basesubstitution, producing a new codon that specifies methionine. Thecodons that specify leucine are UUA, UUG, CUU, CUC, CUA, and CUG.The only codon that specifies methionine is AUG. Which of thesecorrectly describes the mutation? Please show how you got theanswer.
A. a transition at the third nucleotide position of a leucinecodon
B. a transition at the first nucleotide position of one of theleucine codons
C. a transversion at the third nucleotide position of a leucinecodon
D. a transversion at the first nucleotide position of a leucinecodon
