Question

Quizplus · Accepted Answer

A-helices and B-strands are both examples of secondary structure in proteins, which refers to the local folding patterns of the polypeptide backbone. The primary structure is simply the linear sequence of amino acids, while the tertiary and quaternary structures refer to the overall 3D structure of the protein and the interactions between multiple subunits, respectively.
