Assertion: Restriction enzymes recognize palindromic sequence.
Reason: Palindromic sequences read same in both directions of the two strands.
Answer & explanation
Correct answer: option 2
The palindrome in DNA is a sequence of base pairs that reads same on the two strands when orientation of reading strand is kept same. Restriction enzymes cut the strand of DNA a little away from the centre of the palindrome sites, but between the same two bases on opposite strands.
