Question

Assertion(A): Restriction endonucleases function by 'inspecting' the length of a DNA sequence to find the specific recognition sequence.

Reason (R): The sequences recognised by endonucleases are typically 4-6 nucleotides long and are palindromes, also called palindromic nucleotide sequences.

पर्याय

• 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:

Restriction endonucleases inspect DNA to find their recognition sequences. These sequences are typically 4–6 nucleotides long and palindromic.
