Question

Even after disruption of all the hydrogens bonds, which structural level of a protein molecule still remains intact?

• A. Teritary structure
• B. Primary structure
• C. Secondary structure
• D. Quaternary structure

Answer 1

Answer: (B)

Primary structure

Primary structure of the protein is formed by the covalent bond i.e., peptide bonds. hence, after disruption of hydrogen bond its structure will remain intact. Whereas secondary, tertiary and quaternary structure possess hydrogen bond. Thus, the correct answer is option B.
