A. Restriction enzymes and host organism
B. Ligases and vectors
C. Ribosome
D. Polymerase enzyme
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A, B and D only
A. Restriction enzymes and host organism — True.
B. Ligases and vectors — True.

NCERT Extract:
Tools of Recombinant DNA Technology – “… Now we know from the foregoing discussion that genetic engineering or recombinant DNA technology can be accomplished only if we have the key tools, i.e., restriction enzymes, polymerase enzymes, ligases, vectors and the host organism. Let us try to understand some of these in detail.”
