B) secondary
C) tertiary
D) quaternary
E) globular

Question

Quizplus · Accepted Answer

Long-range interactions between residues on a single polypeptide chain are characteristic of tertiary structure. This includes interactions between amino acid side chains that are distant from each other in the linear sequence, such as disulfide bonds or hydrogen bonds between residues far apart in the protein sequence. Primary structure refers to the linear sequence of amino acids, secondary structure refers to local folding patterns such as alpha helices or beta sheets, quaternary structure refers to the arrangement of multiple subunits in a protein complex, and globular refers to the overall compact, orb-like shape of some proteins.
