Work on SAE Record Books.. What happens if there is a mistake (. mutation. ). in the DNA code?. Possibly proteins won’t be made or are made improperly.. If the mutations occur in the gametes, the offspring’s DNA will be affected positively, negatively, or neutrally.. Polypeptides made up of amino acids. Proteins are polypeptides, numerous amino acids. First Recall Proteins------. **Peptide Bond between amino acids. **Notice the “R” group. It’s a group of molecules that determines the amino acid..
