Match List-I with List-II. List-I (Codons) List-II (Properties/Amino acids) A. AUG I. Phenylalanine B. UUU II. Terminator codon C. UAA III. Lysine D. AAA IV. Dual function Choose the correct answer from the options given below:

Options

  1. AA-IV, B-III, C-II, D-I
  2. BA-IV, B-I, C-II, D-III
  3. CA-II, B-I, C-IV, D-III
  4. DA-IV, B-II, C-I, D-III

Correct answer

B. A-IV, B-I, C-II, D-III

Step-by-step solution

According to the properties of the genetic code: - AUG has dual functions. It codes for the amino acid Methionine and also acts as the initiator codon. (A matches with IV) - UUU codes for the amino acid Phenylalanine. (B matches with I) - UAA, UAG, and UGA are stop or terminator codons that do not code for any amino acid. (C matches with II) - AAA and AAG code for the amino acid Lysine. (D matches with III) Thus, the correct matching is A-IV, B-I, C-II, D-III. Answer: A-IV, B-I, C-II, D-III
