​Important Point
Recombinant DNA Technology:
​Recombinant DNA technology is the process of joining together DNA molecules from two different species.
The recombined DNA molecule is then inserted into a host organism to produce new genetic combinations that are of value to science, the medicine sector, agriculture, and industrial use.
