NEET Zoology Genetic Engineering MCQ Question
Which of the following statements regarding genetic engineering and recombinant DNA technology is correct?
Recombinant DNA is formed by joining DNA fragments using DNA ligase.
Antibiotic resistance genes are primarily used for cloning purposes.
Thermostable DNA polymerase is used to inactivate genes during cloning.
Restriction enzymes can only cut DNA at specific sequences without any other function.
Correct Answer
Detailed Explanation
Recombinant DNA is indeed formed by linking DNA fragments with the help of DNA ligase, as stated in the context. The other statements contain inaccuracies regarding the roles of antibiotic resistance genes, thermostable polymerase, and restriction enzymes.
