Question

$\beta$-pleated sheet structure of protein shows maximum extension. Intermolecular hydrogen bonding is present in them.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (B)

If both assertion and reason are true but reason is not the correct explanation of assertion

Answer 2

In $\beta$ -pleated sheet structure, the polypeptide chains are held together by intermolecular H-bonds. Extension and contraction of $\beta$ -pleated sheet structure of protein depends on the size of $R$.
