If the mRNA codon is UAU, which amino acid is encoded?

Explanation:
The genetic code maps each mRNA triplet to a specific amino acid, and UAU is one of the codons for tyrosine. Tyrosine is encoded by UAU and UAC, so when the mRNA shows UAU, the amino acid inserted is tyrosine. The other options correspond to different codons: valine uses GUU/GUC/GUA/GUG, tryptophan uses UGG, and phenylalanine uses UUU/UUC.
