Question

Given below are two statements labelled as Assertion (A) and Reason (R).
Assertion (A): Proteins are made up of alpha amino acids.
Reason (R): During denaturation, secondary and tertiary structure of proteins are destroyed.

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is not the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is B Both A and R are true but R is not the correct explanation of A

During denaturation, secondary and tertiary structure of proteins are destroyed but the primary structure containing alpha amino acids does not change. So, assertion is true, reason is true but reason is not the correct explanation of assertion.
So, the correct answer is option (b).
