Which of the following concerning protein structure is not correct?
A) The primary structure of a protein is the sequence of amino acids linked together by peptide bonds.
B) Hydrogen bonds between amide linkages in the protein backbone define protein secondary structure.
C) Helices and sheets are common tertiary structures in proteins.
D) How a protein folds into its overall 3-dimensional shape is referred to as the protein tertiary structure.
E) In cases where more than one polypeptide chain makes up the protein,the interaction of the different chains is referred to as the quaternary structure.

Question

Quizplus · Accepted Answer

Helices and sheets are examples of secondary structures in proteins, not tertiary structures. Tertiary structure refers to the overall 3D shape of a single protein molecule, including the arrangement of secondary structures and the position of amino acid side chains.
