🧬 Biotechnology: A Comprehensive Definition and Advanced Applications

📖 History and Evolution of Biotechnology

Traditional biotechnology has existed for centuries; humans have long used fermentation processes to produce bread, cheese, vinegar, and alcoholic beverages. In the 20th century, particularly after the discovery of the DNA structure by Watson and Crick in 1953, biotechnology entered a new era. The development of genetic engineering techniques in the 1970s and 1980s—such as recombinant DNA (rDNA) technology, the production of the first human insulin by bacteria, and the creation of genetically modified (GM) crops—opened new horizons in this field.

🌿 Main Branches of Biotechnology

🔴 Red Biotechnology (Medical and Pharmaceutical): Production of vaccines, antibiotics, biologics, gene therapy, and molecular diagnostics.
🟢 Green Biotechnology (Agricultural): Development of genetically modified crops with resistance to pests, drought, and enhanced nutritional value.
⚪️ White Biotechnology (Industrial): Use of enzymes and microorganisms for sustainable industrial production, including bioplastics and biofuels.
🔵 Blue Biotechnology (Marine): Exploiting marine organisms for pharmaceuticals, chemicals, and environmental applications.
