Biotechnology
Biotechnology is a science that uses living organisms or their parts to make useful products or solve problems. It combines biology with technology. The term comes from two words — “bio” (life) and “technology” (use of scientific tools). Biotechnology has many applications in different fields like medicine, agriculture, environment, and industry. In this essay, we will understand what biotechnology is, its different types and dimensions, and how it is applied in the real world.
What is Biotechnology?
Biotechnology means using living things such as bacteria, plants, animals, or cells to produce goods or services that benefit humans. It is a fast-growing area of science and engineering. For example, using yeast to make bread and alcohol is an ancient form of biotechnology. Today, modern biotechnology is more advanced and includes gene editing, cloning, making vaccines, producing biofuels, and much more.
