NEET Zoology Recombinant DNA MCQ Question
Which of the following statements about recombinant DNA technology is correct?
Restriction endonucleases cut DNA at specific palindromic sequences, allowing for the creation of recombinant vectors.
Only exonucleases are used to cut DNA into fragments for recombinant DNA technology.
Micro-injection is the only method to introduce recombinant DNA into host cells.
Recombinant DNA can only be formed by using viral vectors for gene transfer.
Correct Answer
Detailed Explanation
Restriction endonucleases function by inspecting DNA sequences and cutting at specific points, which is essential for creating recombinant vectors. This process is fundamental to recombinant DNA technology as described in the NCERT context.
