Solution

The correct option is D All of the above
Recombinant DNA technology (rDNA technology) deals with the manipulation of genes and genetic material by human beings.

It is also known as genetic engineering because it involves cutting and pasting desired DNA fragments and introducing them into the specified hosts for the benefits of human beings.

Hence, introducing a fragment of human DNA into a bacterium (host) via a vector (vector is a molecule capable of carrying foreign DNA) can be referred to as recombinant DNA technology/rDNA technology/genetic engineering.

Human insulin is produced by rDNA technology on a large scale by using genetically modified bacteria.
