Biotechnology is the use of living systems and organisms to develop or make useful products, or any technological application that uses biological systems, living organisms or derivative, to make or modify products or processes for specific use. For thousands of years, humankind has used biotechnology in agriculture, food production and medicine. In the late 20th and early 21st century, biotechnology has expanded to include new and diverse sciences such as genomics, recombinant gene technologies, applied immunology, and development of pharmaceutical therapies and diagnostic tests.
Various definitions of ‘biotechnology’
The concept of 'biotech' or 'biotechnology' encompasses a wide range of procedures (and history) for modifying living organisms according to human purposes — going back to domestication of animals, cultivation of plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering as well as cell and tissue culture technologies. Biotechnology is defined by the American Chemical Society as the application of biological organisms, systems, or processes by various industries to learning about the science of life and the improvement of the value of materials and organisms such as pharmaceuticals, crops, and livestock. In other words, biotechnology can be defined as the mere application of technical advances in life science to develop commercial products.
