Question

What is the primary definition of recombinant DNA technology?

Options

• The spontaneous mutation of genomic sequences inside living bacteria under ultraviolet radiation

• The isolation of RNA molecules to directly synthesize synthetic enzymes in cell-free systems

• The degradation of unwanted foreign genes using cellular nucleases

• The technique of joining DNA from two different sources and introducing it into a host organism to produce useful products

Answer 1

Recombinant DNA technology refers to the technique of joining DNA molecules from two different sources and inserting them into a host organism. This process enables the host to multiply the target gene and manufacture desired products such as insulin, enzymes, and vaccines.
