click to select all of the areas that include a complete peptide bond.

Explanation:

Step1: Recall peptide - bond structure

A peptide bond is formed between the carboxyl group ($-COOH$) of one amino - acid and the amino group ($-NH_2$) of another amino - acid, with the loss of a water molecule. The general structure of a peptide bond is $-CO - NH-$.

Step2: Identify peptide - bond regions in the given structure

In the provided polypeptide chain structure, the peptide bonds are located between each pair of adjacent amino - acids. They are the $-CO - NH-$ linkages.

Answer:

All the $-CO - NH-$ regions in the polypeptide chain should be selected.
