Chapter 9: Problem 4

If a messenger RNA codon is UAC, which of the following would be the complementary anticodon triplet in the transfer RNA? (A) ATG (B) \(\mathrm{AUC}\) (C) \(\mathrm{AUG}\) (D) ATT

Short Answer

Expert verified
The complementary anticodon triplet for the given mRNA codon UAC is \(\mathrm{AUG}\), which corresponds to the correct answer (C).

Step by step solution

01

Written codon

We are given the mRNA codon UAC.
02

Base pairing rules

Remember the base pairing rules for mRNA to tRNA: - A pairs with U - C pairs with G - G pairs with C - U pairs with A
03

Find the complementary anticodon triplet

Using the base pairing rules, the anticodon triplet that complements the given mRNA codon (UAC) can be found as follows: - U pairs with A - A pairs with U - C pairs with G So, the complementary anticodon triplet is AUG.
04

Choose the correct answer

Now that we found the anticodon triplet (AUG), let's identify the correct answer from the given options: (A) ATG (B) \(\mathrm{AUC}\) (C) \(\mathrm{AUG}\) (D) ATT The correct answer is (C) \(\mathrm{AUG}\).
