The anticodon of a tRNA is 5'UUG.What codon(s)can be recognized,theoretically,by this tRNA?

Question

Quizplus · Accepted Answer

The anticodon sequence of a tRNA binds to the codon sequence on mRNA during mRNA translation. The codon is a three-nucleotide sequence on mRNA. The pairing of the first two nucleotides in the codons follows the Watson-Crick base pairing rules. Therefore, the anticodon 5'UUG can bind to the codons 5'CAA and 5'CAG based on the following pairing rules: U>A, C>G, G>C, and A>U. So, the correct choice is B, where both 5'CAA and 5'CAG can be recognized by the tRNA with the anticodon 5'UUG.

The Anticodon of a TRNA Is 5'UUG
