The correct answer is: If both assertion and reason are false.
The relationship between the sequence of amino acids in a polypeptide and nucleotide sequence of DNA or $m \mathrm{RNA}$ is called genetic code. The genetic code is triplet. One codon codes for only one amino acid, hence it is unambiguous and specific. Some amino acids are coded by more than one codon, hence the code is degenerate.
