Assertion : One codon may code for more than one amino acid....

Assertion : One codon may code for more than one amino acid. Reason: A codon is degenerate and ambiguous.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

The relationship between the sequence of amino acids in a polypeptide and nucleotide sequence of DNA or mRNAm \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.
