Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Restriction endonucleases inspect the length of a DNA sequence and cut each of the two strands of double helix at specific points. Reason (R): Restriction endonucleases can recognize palindromic nucleotide sequences in the DNA and make cuts in the sugar-phosphate backbones. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. is true but (R) is false.
4. is false but (R) is true.
