How do start codons work?

The ribosome reads the mRNA in three nucleotide codons, beginning with the start codon, AUG, which codes for the amino acid methionine. The order of the bases within the codons determines which amino acid will be added to the growing protein by the ribosome.

Is Aug always the start codon?

START codons The codon AUG is called the START codon as it the first codon in the transcribed mRNA that undergoes translation. AUG is the most common START codon and it codes for the amino acid methionine (Met) in eukaryotes and formyl methionine (fMet) in prokaryotes.
