What is the anticodon on tRNA that pairs with the codon AAA?

Explanation:
During translation, the tRNA anticodon pairs with the mRNA codon in an antiparallel, complementary fashion. For a codon made of three adenines (AAA), the complementary RNA sequence is UUU, since A pairs with U in RNA. So the anticodon that recognizes AAA is UUU, which brings the correct amino acid to the growing polypeptide chain. The other sequences don’t match AAA as the proper complement, so they wouldn’t pair with that codon.
