Assertion : Restriction endonucleases are also called 'molecular scissors'. Reason : When fragments generated by restriction endonucleases are mixed, they join together due to their sticky ends.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Restriction enzymes are also called "molecular scissors" as they cleave DNA at or near specific recognition sequences known as restriction sites. These enzymes make one incision on each of the two strands of DNA and are also called restriction endonucleases. Restriction endonuclease are molecular scissors which cut a DNA molecule within certain specific site called restriction site. Common restriction endonucleases are EcoRI, Barn II, Hind III etc. When the DNA fragments are mixed they joint to each other due to free 5 phosphate group and \(3 \mathrm{OH}\) group.
