Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : When a particular restriction enzyme cuts strand of DNA, overhanging stretches or sticky ends are formed. Reason (R) : Some restriction enzymes cut the strand of DNA a little away from the centre of palindromic site. In the light of the above statements, choose the correct answer from the options

Options

  1. ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
  2. BBoth (A) and (R) are correct but (R) is not the correct explanation of ( A )
  3. C(A) is correct but (R) is not correct
  4. D(A) is not correct but (R) is correct

Correct answer

A. Both (A) and (R) are correct and (R) is the correct explanation of (A)

Step-by-step solution

With the help of most restriction enzymes sticky ends in DNA can be created. The flanking region in DNA can be formed due to cutting of DNA strand little away from restriction site.
