The roots of biotechnology are ancient, often referred to as "traditional biotechnology." Long before the structure of DNA was discovered, humans utilized biological agents for survival. The Sumerians and Egyptians practiced fermentation to produce bread, beer, and wine. In ancient India, as noted in many historical accounts, the practice of Ayurveda utilized plant extracts for medicinal purposes. However, the transition from these empirical practices to a precise science occurred in the 20th century. The discovery of the double-helix structure of DNA by Watson and Crick in 1953 marked the pivotal moment, shifting biotechnology from the manipulation of whole organisms to the manipulation of genetic material itself. This shift gave rise to "modern biotechnology" or genetic engineering. | Unit | Title | Key Topics Covered
