E) Number of domains

Question

Quizplus · Accepted Answer

Tertiary protein structure refers to the spatial arrangement of atoms in a polypeptide chain, taking into account the folding of secondary structures and the overall shape of the protein. This includes the 3D positioning of side chains, disulfide bonds, and other features that contribute to the protein's stability and function.

Answer: E
 Tertiary protein structure can also refer to the organization of domains within a single polypeptide chain, or the association of multiple subunits to form a larger protein complex. A domain is a region of a protein that can fold independently and often has a specific function, such as binding to a ligand or catalyzing a reaction. The arrangement of domains in a protein can influence its overall stability, specificity, and regulation.
