Biotechnology refers to the application of biological systems, living organisms, or derivatives thereof, to create or modify products, or to improve plants or animals, for the benefit of human beings. It involves the use of technology to manipulate and understand the genetic material of organisms and modify their traits in a controlled manner, leading to the creation of new and improved products and technologies. Biotechnology has a wide range of applications in fields such as medicine, agriculture, and environmental science, among others. It encompasses various techniques like genetic engineering, recombinant DNA technology, tissue culture, and fermentation, and has the potential to provide solutions to many global challenges such as disease, food security, and environmental degradation.
