A tRNA molecule has the anticodon UAC. Which mRNA codon does it bind to?
Answer and explanation
Correct answer: D. AUG
- Step 1: Anticodon and codon are complementary.
- Step 2: U pairs with A, A with U and C with G, so UAC binds AUG.
Answer
AUG.
Why not the others: UAC: the codon is complementary, not identical. ATG: mRNA has uracil, not thymine. TAC: this is a DNA triplet.
