Assertion : Each restriction endonuclease funtions by 'inspecting' the length of a DNA sequence
Reason:Once it finds its specific recognition sequence, it will bind to the DNA and cut hydrogen bonds

A

If both assertion and reason are true and the reason is the correct explanation of the assertion

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
C
`**` Each restriction endonuclease functions by 'inspecting' the length of a DNA sequence.
`**` Once it finds its specific recognition sequence, it will bind to the DNA and cut each of the two strands of the double helxi at specific points of their sugar phosphate backbones.
