NEET Zoology Recombinant DNA MCQ Question
Which combination of statements about recombinant DNA is correct?
Restriction enzymes cut DNA at specific sequences, and DNA ligase joins DNA fragments.
Endonucleases remove nucleotides only from the ends of DNA strands.
Plasmids cannot act as vectors for DNA transfer.
Restriction enzymes function by cutting DNA at random locations.
Correct Answer
Detailed Explanation
Restriction enzymes are known to cut DNA at specific recognition sequences, while DNA ligase is responsible for joining DNA fragments, forming recombinant DNA. This aligns with the definition and roles of these enzymes in biotechnology.
