Which one of the following is the starter codon?
UGA
UAA
UAG
AUG
the codon AUG has dual functions: it codes for the amino acid Methionine (met) and also acts as the initiator codon (starter codon) for protein synthesis. The other three options (UAA, UAG, and UGA) do not code for any amino acids and function as stop terminator codons.
