Answer:
GAU
Explanation:
A mRNA codon is complementary to an tRNA anticodon. Codons are triplet sequences present on an mRNA molecule that a tRNA pairs with, in order to assemble a sequence of amino acids together. This sequence of amino acids is dictated by the order of codon sequences on mRNA.
Base pairing rules indicate that C always pairs with G, and that A always pairs with U (or T in the case of DNA)
Therefore, the codon CUA will pair with GAU.
