There is an increasing demand for genetic engineers in India as well as abroad. Genetic engineers are mainly absorbed in medical and pharmaceutical industries, the agricultural sector, and the research and development departments of the government and private sectors. They can also take up teaching as an option. 

Genetic engineering involves developing hybrid varieties of plants, making a plant disease resistant by transferring genes from a plant that already has the characteristic, introducing Genetically Modified foods by changing the colour, size, texture of the produce of plants such as fruits and vegetables. GE in humans can be to correct severe hereditary defects by introducing normal genes into cells in place of missing or defective ones. 

A team headed by Ian Wilmut and his colleagues at the Roslin Institute in Edinburgh, Scotland made history when they produced a lamp named Dolly, an exact genetic copy or clone of a sheep. This landmark discovery of the regeneration of an exact replica of a whole animal by transferring nuclei from the cells of that animal to unfertilized eggs of another animal, without the help of a male counterpart, has given researches a wide area open to be discovered. With this discovery, genetic engineering has become globally recognized.
