Assertion: Each restriction endonuclease recognises a specific pallindromic nucleotide sequence in the DNA
Reason :The pallindrome in DNA is a sequence of base pairs that reads same on the two strands in a particular direction

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:
B
`**` Each restriction endonculease recognises a specific palindromic nucleotide sequences is the DNA
`**` The palindrome in DNA is a sequence of base pairs that reads same on the two strands when oritentation of reading kept the same
