Answer:
UCG
Step-by-step explanation:
In DNA, Thiamine pairs with Adenine while Cytosine pairs with Guanine. However, it is important to note that Uracil takes the place of Thiamine in RNA. Therefore the A in the mRNA will pair in U in the tRNA. tRNA uses the anticodon region to read the mRNA and a match means the specific tRNA brings in the requisite amino acid.
