Given below are two statements: Statement I: Restriction endonucleases recognise specific sequence to cut DNA known as palindromic nucleotide sequence. Statement II: Restriction endonucleases cut the DNA strand a little away from the centre of the palindromic site. In the light of the above statements, choose the most appropriate answer from the options given below.
Both Statement I and Statement II are correct
Both Statement I and Statement II are incorrect
Statement I is correct but Statement II is incorrect
Statement I is incorrect but Statement II is correct
Each restriction endonuclease recognises a specific palindromic nucleotide sequence in the DNA. It binds to the DNA and cuts each of the two strands of the double helix at specific points. Restriction enzymes cut the strand of DNA a little away from the centre of the palindromic site, but between the same two bases on the opposite strands. Thus, both statements I and II are correct.
