Question

Match the following (Anticodons).

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

Hint:

Start codon AUG codes for Methionine and its anticodon is UAC.

Answer 1

The Correct Option is C

Concept: Anticodon present on tRNA is complementary to the codon present on mRNA.

Step 1: Methionine.
Codon: \[ AUG \] Anticodon: \[ UAC \] Hence: \[ A \rightarrow IV \]

Step 2: Tryptophan.
Codon: \[ UGG \] Anticodon: \[ ACC \] Hence: \[ B \rightarrow III \]

Step 3: Tyrosine.
Codon: \[ UAU \text{ or } UAC \] Corresponding anticodon: \[ AUA \text{ or } AUG \] Hence: \[ C \rightarrow II \]

Step 4: Serine.
One anticodon for serine: \[ UCA \] Hence: \[ D \rightarrow I \] Final matching: \[ \boxed{A-IV,\;B-III,\;C-II,\;D-I} \] Hence option (C).
