What is the tRNA anticodon for tyrosine?

Explanation:
Tyrosine is encoded on the genetic code by the mRNA codons UAU and UAC. A tRNA recognizes a codon through complementary, antiparallel base pairing between the codon and its anticodon. The anticodon that pairs with the UAU codon is AUA, so the tRNA that carries tyrosine would have anticodon AUA. The other sequences don’t match the tyrosine codons: UAU is itself a tyrosine codon, AUG codes for methionine (start codon), and CAU corresponds to a different amino acid.
