Question

Assertion (A): DNA is associated with basic proteins called histones.

Reason (R): Negatively charged DNA is wrapped around histone octamers to form a structure called nucleosome.

Options

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

Explanation:

Both statements are true. Positively charged histone octamers bind negatively charged DNA, which wraps around them to form nucleosomes.
