NEET Zoology Genetic Engineering Assertion Reason Question
Assertion (A): The use of restriction endonucleases is essential in genetic engineering for creating recombinant DNA. | Reason (R): Restriction endonucleases cut DNA at specific sequences, allowing the separation of DNA fragments by gel electrophoresis.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
Restriction endonucleases cut DNA at specific sequences, which is essential for creating recombinant DNA by allowing specific fragments to be isolated and used. Gel electrophoresis further helps in separating these fragments, supporting the role of restriction endonucleases in genetic engineering.
