The codon AUG must be identified.
AUG is the start codon (signals start of translation) and recruits the initiator tRNA carrying methionine (or fMet in bacteria). The other options are incorrect: peptide bonds form between amino acids (not mRNA subunits) after initiation, Cys is not required as the initiator amino acid, and adding a water molecule is not how translation begins.
