Question

In the process of recombinant DNA technology, the isolated foreign DNA is inserted into another DNA molecule known as

• A. Protein vector
• B. RNA vector
• C. Cloning vector
• D. None of the above

Answer 1

Answer: (C)

Cloning vector

Plasmids are the self-replicating circular DNA molecules in the bacterial cells. These plasmids are used for the transfer of the desired genes into the other cells and are known as vectors. The desired foreign DNA segment can be introduced into these vectors with the help of restriction enzymes and ligase. They are used in the recombinant DNA technology, for the introduction of the gene into the host cell to produce useful products.

Thus, the correct answer is option C.
