True or false: Generally, the total number of nonpolar amino acids has a greater affect on protein structure than the exact order of amino acids in a polypeptide chain. - CORRECT ANSWER-False. The order in which amino acids are linked is unique for each protein and is the most important factor in determining the overall protein factor. True or False: The "polypeptide backbone" refers to all atoms in a polypeptide chain, except for those that form the peptide bonds. - CORRECT ANSWER-False...
