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.
Adjacent to a frequently-asked paragraph in the same chapter.
Which of the following is not considered a key tool in recombinant DNA technology?
Correct answer: C — tRNA molecules
NCERT lists restriction enzymes, polymerases, ligases, vectors, and host organisms as essential tools. tRNA is not included.
