    Question

    Which of the following is NOT a feature of recombinant

    DNA technology?
    A Gene cloning Correct Answer Incorrect Answer
    B Use of restriction enzymes Correct Answer Incorrect Answer
    C Isolation of entire genome Correct Answer Incorrect Answer
    D Formation of recombinant plasmids Correct Answer Incorrect Answer

    Solution

    Recombinant DNA (rDNA) technology involves modifying genetic material to create new DNA combinations for various applications. Gene cloning (Option 1): It is a key aspect of rDNA technology where a specific gene is copied and amplified. Use of restriction enzymes (Option 2): These enzymes cut DNA at specific sequences, allowing gene insertion. Formation of recombinant plasmids (Option 4): Plasmids act as vectors to transfer foreign genes into host cells. Isolation of the entire genome (Option 3) is NOT a feature because rDNA technology focuses on isolating specific genes rather than the whole genome. Thus, the correct answer is option (3).
