NEET Zoology (general) MCQ Question
Which of the following combinations correctly describe components and processes involved in recombinant DNA technology?
Restriction endonucleases cut DNA, DNA ligase joins DNA fragments, and plasmids serve as vectors.
Thermostable DNA polymerase is used only for DNA replication, and bioreactors are not involved in genetic engineering.
Recombinant DNA technology is limited to the production of vaccines and does not include gene editing.
DNA amplification is achieved using standard DNA polymerase, and vectors are unnecessary for gene transfer.
Correct Answer
Detailed Explanation
Option A accurately describes the roles of restriction endonucleases, DNA ligase, and plasmids in recombinant DNA technology, as outlined in the NCERT content. Options B, C, and D contain inaccuracies regarding the applications and components of the technology.
