Answer

Brief Explanations:

In protein translation, the start codon AUG (which codes for methionine) is recognized by the ribosome - tRNA complex to initiate the process. Adding a water molecule is related to protein degradation or some post - translational modifications, not initiation. Peptide bonds form between amino acids during elongation, not between mRNA subunits. While tRNA picks up amino acids, the key event for initiation is start - codon recognition.

Answer:

The codon AUG must be identified.
