Study Notes
Biotechnology Overview
- Biotechnology merges "bio" (Greek for "life") and "technology" (rooted in Greek words techne and logos meaning "art, skill, craft" and "word, thought").
- It encompasses the use of organisms and their components for specific applications, integrating modern lab methods with traditional techniques in agriculture and food.
- The discipline includes genetic modification, domestication, animal husbandry, plant cultivation, and selective breeding.
Historical Milestones in Biotechnology
- Domestication of plants and animals began over 10,000 years ago as early humans relied on certain crops for sustenance.
- 8000-4000 B.C.E: Domestication of crops and livestock; potatoes cultivated for food.
- 2000 B.C.E: Egyptians utilize yeast for bread leavening and beer fermentation; cheese production starts in Sumeria, China, and Egypt.
- 500 B.C.E: The Chinese apply moldy soybean curds as an antibiotic for treating boils.
- 100 C.E: First recorded insecticide made from powdered chrysanthemums in China.
Significant Discoveries and Innovations
- 1797: Edward Jenner develops the first vaccination for smallpox.
- 1830-1833: Discovery of proteins and the first enzyme isolation.
- 1857: Louis Pasteur links microbes to fermentation, supporting germ theory.
- 1865: Gregor Mendel establishes the basic laws of heredity through flower studies.
Advancements in Genetic Understanding
- 1915: Discovery of bacteriophages that infect only bacteria.
- 1919: Term "biotechnology" first appears in print.
- 1928: Alexander Fleming discovers penicillin, marking a breakthrough in antibiotics.
- 1944: Evidence presented that DNA carries genetic information.
- 1953: Watson and Crick describe DNA's double helical structure, earning a Nobel Prize in 1962.
Modern Biotechnological Breakthroughs
- 1971: The first complete gene synthesis achieved (gene cloning).
- 1973: Cohen and Boyer pioneer genetic engineering techniques using restriction enzymes.
- 1986: First recombinant vaccine for hepatitis B approved; first anti-cancer drug interferon produced through biotechnology.
- 1990: Launch of the Human Genome Project to map all human genes.
- 1997: Birth of Dolly, the first adult cell clone.
- 2003: SARS virus sequenced quickly after detection, highlighting rapid response capabilities in biotech.
Recent Developments
- 2004: First cloned pet, a kitten named Copy Cat.
- 2004: Avastin, a targeted biological therapy, receives FDA approval.
- 2006: Vaccine for human papillomavirus, linked to cervical cancer, approved using recombinant DNA technology.
