Which one of the following is the starter codon?

Explanation

Polypeptide synthesis is signaled by two initiator codons or start codons, i.e., AUG (methionine codon) and rarely by GUG (valine codon). The starter codon is "AUG." It serves as the initiation codon and codes for the amino acid methionine in eukaryotes and, in most cases, in prokaryotes. It also signals the beginning of protein synthesis or translation in the ribosome. The AUG codon is often referred to as the "start codon." The other codons mentioned, UAA, UAG, and UGA, are stop codons that signal the termination of protein synthesis.
