The significance of AUG codon is that it signals the ribosome to start translation.
Explanation: Codons are three nucleotides sequence found on the mRNA strand that codes for a specific amino acid. There are 64 codons, one is the start codon, three are stop codons while 61 codes for twenty amino acids. AUG is the start codon which signals the ribosome to start protein synthesis. The AUG codon also codes for amino acid methionine.
