What is Biotechnology? |Definition, Types, Examples, and Applications Photo by:genflowbio| Biotechnology is a field that has been around for centuries. It is the use of biological systems found in organisms or the use of the living organisms themselves to make technological advances and adapt those technologies to various fields. Biotechnology has become an essential part of modern medicine, agriculture, and industry. It has been used to develop new products, methods, and organisms intended to improve human health and society. The most prominent area of biotechnology is the production of therapeutic proteins and other drugs through genetic engineering. Biotechnology has enabled scientists to manipulate the genetic makeup of organisms to produce new products, such as insulin, growth hormones, and vaccines. Biotechnology has also been used to develop new crops that are more resistant to pests and diseases, and to produce biofuels that are more environmentally friendly than fossil fuel
