The RNA codon for methionine is 5′-AUG-3′. Which of the following is the anticodon in the correct methionyl-tRNA?
A) 5′-CAT-3′
B) 5′-CAU-3′
C) 5′-GAU-3′
D) 5′-TAC-3′
E) 5′-UAC-3′

Question

Quizplus · Accepted Answer

The anticodon in the correct methionyl-tRNA is 5′-CAU-3′ because it is complementary to the RNA codon for methionine, which is 5′-AUG-3′. The correct anticodon for any given codon is the antiparallel complimentary sequence. Therefore, the anticodon for methionine would be 5′-CAU-3′.

The RNA Codon for Methionine Is 5′-AUG-3′
