Biotechnology and Genetic Engineering: An Overview
Biotechnology encompasses the application of biological organisms, systems, or processes by various industries to learn about the science of life and the organisms that inhabit the Earth. Genetic engineering, a subset of biotechnology, involves the manipulation of an organism’s genetic material to alter its characteristics or functions.
Historical Development
The origins of biotechnology can be traced back to ancient practices such as fermentation and selective breeding. Modern biotechnology emerged in the mid-20th century with the discovery of the structure of DNA and the development of recombinant DNA technology. Genetic engineering gained prominence in the 1970s with the invention of gene cloning and gene editing techniques.
