Which DNA template letters correspond to the amino acid methionine?

Explanation:
Methionine is encoded by the mRNA codon AUG. During transcription, the DNA template strand is read to produce an RNA sequence that is complementary to it. To yield AUG in the mRNA, the template must present the complementary bases TAC (so that RNA polymerase builds AUG). Therefore the DNA template letters are tac. The other sequences would lead to different mRNA codons and thus different amino acids, so they don’t code for methionine.
