Question

Quizplus · Accepted Answer

Hydrogen bonding between -C=O groups and NH- groups in the backbone of a protein determines the secondary structure, which includes alpha helices and beta sheets. Tertiary structure is determined by interactions between the side chains of amino acids, and quaternary structure refers to the arrangement of multiple protein subunits. The primary structure is simply the linear sequence of amino acids in the polypeptide chain. Therefore, the correct answer is B) secondary structure.
