·      Biotechnology is the application to industry of advances made in the techniques and instruments of research in the biological science. The use of living organisms or of substances obtained from them in industry is known as Biotechnology.

·      It is closely linked to the development in the 1970s of genetic engineering (the directed alternation of genetic material). Substances that have been produced in this manner include human interferon (a natural virus – fighting substance), human insulin and human growth hormone.

·      Recombinant – DNA techniques made an evident impact on medical diagnosis and oncology. Another important use of genetic engineering is the production of bacteria used to biodegrade oil spills and toxic waste.

·      In 1983, an American company Eli Lily, produced the first genetically engineered insulin called humulin with the help of Escherichia Coli (or E-Coli)
