Recombinant DNA Technology - Recombinant DNA technology or genetic engineering involves the isolation and cloning of genes of interest, production of the necessary gene constructs using appropriate enzymes and then transfer and expression of these genes into an appropriate host organism.

This approach is also called, this technique has been used to achieve the following two broad objectives:

(i) production of recombinant proteins, and

(ii) modification of the organism's metabolic pattern for production of new, modified or more quantity of metabolites.
