1.	Assertion `: beta-` pleated sheet structure of protein shows maximum extension. Reason `:` Intermolecular gydrogen bonding is present in them.A. If both the assertion and reacons are true and reason is a true explanation of the assertion.B. If both the assertion and reasons are true but the reason is not the correct explanation of assertion.C. If the assertion is ture but reason is false.D. If assertion is false but reasion is true.
Answer» Correct Answer - B 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.`
