The codon for the amino acid methionine is AUG.What anticodon on a tRNA molecule will match methionine's codon?

Question

Quizplus · Accepted Answer

The anticodon on tRNA that matches with the AUG codon for methionine is UAC. This is because the pairing of bases between codon and anticodon follows the standard base-pairing rules of A with U (or T) and G with C. Therefore, the anticodon that matches with AUG (which has U in the second position) is UAC (which has A in the second position). Choice A (AUG) is incorrect because it is the same as the codon for methionine, not the anticodon on tRNA. Choice B (ATG) is also incorrect because it is a different sequence of RNA bases that does not match with methionine. Choice C (TAC) and E (UAG) are also incorrect because they do not follow the standard base-pairing rules for forming a complementary base pair with the codon AUG on mRNA.
