Use the codon chart below to determine which amino acid matches with the codon uac uac: (this is for flvs students who have taken biology 1)

UAC do not codes for an amino acid but it is a sequence of three RNA bases. It ensures that the correct amino acid is incorporated into a developing poly peptide chain. As we know this is an RNA sequence, because it comprises of the letter “U” for Uracil, which is specific to RNA  (“T” for Thymine is specific to DNA) and Uracil is not present in DNA>

What we cannot properly asses from your question is this that UAC is a codon from messenger RNA (m-RNA) or an anticodon from transfer RNA (t-RNA).

If it’s a codon, its amino acid it’s encoding for is Tyrosine; it it’s an anticodon, it’s encoding for methionine.

Here is a helpful list of anticodons and codons.
