polypeptides are continuously being formed and degraded. one of these processes is shown. the figure presents the molecular structures of polypeptides. a molecule at the top of the figure has a backbone with six repeats of the following atoms: n, c, c. one r group, of the range r 1 through r 6, is bonded with the first c of each the n, c, c repeats. an arrow that is joined by another arrow labeled h 2 o points to two shorter molecules, each with only three repeats of the atoms: n, c, c. one of the shorter molecules has r groups r 1, r 2, and r 3. the other molecule has r groups r 4, r 5, and r 6. figure 1. polypeptide reaction which statement is the most accurate description of the reaction shown in figure 1?
