By the process of the translation mRNA turns into protein as mRNA is considered as blueprint of the protein. During translation tRNA contains anti-codons or amino acid this anti-codon is correspond to the codon of mRNA.
The anticodon of tRNA which is present at the accept site or anticodon of tRNA molecule is complementary to the codon present in the mRNA which means A pairs with U and G pairs with C only.
Thus, the correct answer would be - option D) UAC.
