You Disrupt All Hydrogen Bonds in a Protein

Question

You disrupt all hydrogen bonds in a protein.What level of structure will be preserved?
A)secondary structure
B)primary structure
C)tertiary structure
D)quaternary structure

Accepted Answer

Hydrogen bonds play an important role in stabilizing the secondary and tertiary structures of proteins. Disrupting all hydrogen bonds in a protein would lead to unfolding of the protein and loss of both secondary and tertiary structures. However, the primary structure, which is the linear sequence of amino acids, would remain intact. Therefore, the best choice is B, which is the primary structure.
