Detailed explanation-1: -The tertiary structure is primarily due to interactions between the R groups of the amino acids that make up the protein.

Detailed explanation-2: -R groups interact to form bonds or salt bridges-This statement describes tertiary and quaternary structure of proteins.

Detailed explanation-3: -Quaternary structure is held together by noncovalent bonds between complementary surface hydrophobic and hydrophilic regions on the polypeptide subunits. Additionally, acidic and basic side chains can form salt linkages.

Detailed explanation-4: -Quaternary structure in proteins is the most intricate degree of organization still considered a single molecule. To be considered to have quaternary structure, a protein must have two or more peptide chains forming subunits. The subunits can be different or identical, and in most cases they are arranged symmetrically.
