Assertion : Restriction endonuclease rec...

Assertion : Restriction endonuclease recognize short palindromic. Sequence and cut at specific sites.
Reason : When a restriction endonuclease acts on Palindrome, it cleaves both the the strands of DNA molecules.

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

Text Solution

Verified by Experts

The correct Answer is:
B
Restriction endonuclease is the enzymes that cut DNA at specific site. They usually read palindromic sequences i.e. read same in both the direction. Restriction endonuclease cuts both the strands of DNA either forming blunt end staggered end.
