Question

Which of the following contains the key tools for recombinant DNA technology?
(i) Restriction endonucleases, ligases, vectors(ii) Ligases, host organism, polymerase enzymes(iii) Vectors, Taq polymerase, primers(iv) Restriction exonucleases, ligases, primers, bioreactors

• A. (i), (ii) and (iii)
• B. (i) and (ii)
• C. (i), (iii) and (iv)
• D. (iii) and (iv)

Answer 1

Answer: (B)

(i) and (ii)

Key tools for recombinant DNA technology:

• Restriction endonuclease enzyme and DNA ligases for recombinant DNA production.
• Vectors that help in carrying and integrating the desired gene.
• Host organism is that one in which recombinant DNA is introduced.
• Polymerase enzymes
• So, the correct option is 'Option B' .
