Assertion : beta- pleated sheet structur...

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.

Text Solution

Verified by Experts

The correct Answer is:
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.`
