Figure 1.3: Impact of Biotechnology on different fields & human life.

Animal sciences- One of the early application of biotechnology in animal science is developing method to separate cheese and other food products from milk by enzyme and microbes. Genetic engineering in conjugation with cell biology and biochemistry has developed multiple products of animal origin. Transgenic animal strains with desired phenotype such as high milk yielding animals, fishes and hens with more fat content. A detail description of other biotechnology application in animal sciences is discussed later.

Medicine and Medical Sciences- Biotechnology helped identification of drug like molecules, antibiotics and other medicines. At present a number of antibiotics are being produced by fermentation or in cell based systems. Apart from antibiotic, vaccine, diagnostic kits and other immunotherapy are gift of biotechnological advancement. Development of artificial limb, arms, heart and medical procedures to perform open-heart operation, dialysis, artificial insemination, test-tube baby and other medical procedures.
