(USMLoid) The single tyrosine tRNA recognises both of the tyrosine codons - UAU and UAC. Which of the following is therefore the anticodon sequence of this tRNA? את שני הקודונים עבור טירוזין – UAU, UAC – מזהה tRNA יחיד. אם כך, מי מהבאים הינו רצף האנטי-קודון של tRNA זה?

This is a question about the wobble position - and yes, it corresponds almost exactly to a USMLE question. However, you can answer it without remembering almost anything about that table of non-canonical base-pairings at the wobble position. Just think it through. All the choices except the correct one are eliminated even if you just remember that a base never base-pairs with itself. The correct answer is: 5' - GUA - 3'
