The m
RNA sequence AUG, which specifies methionine, the first
amino acid used in the
translation process. (Occasionally GUG, valine, is recognized as an
initiation codon).

translation of m
RNA.
Full article >>>Initiation Codon: The
codon at which
translation of a
polypeptide chain is initiated. This is usually the first AUG triplet in the m
RNA molecule from the 5' end, where the
ribosome binds to the cap and begins to scan in a 3' direction.
