Question
Indicate whether the following statements describe the primary, secondary, tertiary, or quaternary protein structure. (More than one can apply to the below) A) R groups interact to form disulfide bonds or ionic bonds. B) Peptide bonds join the amino acids in a polypeptide chain. C) Several polypeptide chains in a beta-pleated sheet are held together by hydrogen bonds between adjacent chains. D) Hydrogen bonding between amino acids in the same polypeptide gives a coiled shape to the protein.

A) R groups interact to form disulfide or ionic bonds
The R-group interactions happens only in the higher order protein structure minimum must be tertiary to do the same. Hence the correct answer for A will be both tertiary and quarternary
B) Peptide bonds join the amino acids in a polypeptide chain.
Peptide bond linking happens only in the single monomer polymer, therefore correct answer must be primary
C) Several polypeptide chains in a beta-pleated sheet are held together by hydrogen bonds between adjacent chains.
This phenomena occusin the secondary structure
D) Hydrogen bonding between amino acids in the same polypeptide gives a coiled shape to the protein.
For the same polypeptide group, the answer must be Secondary
