Question

Assertion: Scaffold proteins are nonhistone chromosomal proteins.
Reason: They are rich in lysine and arginine.

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

Answer 1

The correct option is C If the assertion is true but the reason is false

Structural nonhistone chromosomal proteins are called scaffold proteins as they constitute the core axis of the chromosome. They contain very little lysine and arginine but instead possess abundant tyrosine and tryptophan types of amino acids. Therefore assertion is true but reason is false.

So, the correct answer is 'If the assertion is true but the reason is false'
