NEET Zoology Recombinant DNA MCQ Question
Which of the following statements correctly describe methods of introducing recombinant DNA into host cells?
Micro-injection involves injecting DNA directly into the nucleus of an animal cell.
Heat shock is primarily used in plant cells to facilitate DNA uptake.
Biolistics uses high-velocity micro-particles coated with DNA to transfer genetic material.
Recombinant DNA can only be introduced using plasmid vectors and no other methods.
Correct Answer
Detailed Explanation
Micro-injection is a method where recombinant DNA is injected directly into the nucleus of an animal cell, while biolistics is suitable for plants. Heat shock is not specifically used for plant cells, and recombinant DNA can be introduced through various methods, not just plasmid vectors.
