Genetic Engineering is the introduction of foreign genes for improving genotype. It is a technique of manipulating prokaryotic and eukaryotic DNA. It allows breaking of a DNA molecule at two desired places to isolate a specific DNA segment and then its insertion in another DNA molecule at a desired position. The product thus obtained is called r DNA and the technique as genetic engineering.
