Biotechnology is a field of science and technology that involves the use of living organisms, cells, and biological systems to produce products and services with practical applications. It encompasses a wide range of techniques and processes that involve the manipulation of biological material to create new products, improve existing ones, or to understand biological processes. The goal of biotechnology is to harness the power of biology to solve problems and improve human health, agriculture, the environment, and industry. Some examples of biotechnology applications include genetic engineering, fermentation, tissue culture, and bioremediation.
