8th Grade Science biotechnology
What is Biotechnology? • The science that manipulates living matter to improve the human condition or environment. • Specifically: The manipulation of matters’ genes.
History of Biotechnology • Newer science as a whole. • Originated to benefit to humans. • New developments being made and it has been said that we have only discovered “the tip of the ice berg” in this science.
History of Biotechnology Cont. • 500 BC: The Chinese use moldy curds as an antibiotic to treat boils • 1883: The rabies vaccine is developed • 1949: Pauling proves that sickle cell anemia is a "molecular disease" caused by a mutation • 1981: 1st mice to be successfully cloned
Uses of Biotechnology: • Medicine: used in the production of medicines and vaccines in large quantities. • Manipulation of bacteria to form new antibiotics. • Medicines can be modified to fight specific diseases. • Ex. Insulin for Diabetes Human DNA is placed inside bacteria to produce insulin.
Uses of Biotechnology Cont. • Genetic Engineering: • Genetic Cloning • Dolly the sheep • Some medical disorders can be corrected through genetic modification. • DNA Testing • Fighting crime through forensic science, paternity/maternity proof, and genetic testing for abnormalities.
Uses of Biotechnology Cont. • Agriculture: • Developed disease resistant crops to improve crop yield and avoid using pesticides. • Developed crops that can grow in different environments. • Bioremediation: process of removing pollution from soil & water. • In North Carolina, preserved and saved the Heritage trees from root rot. • Implanted a mold resistant gene.
Uses of Biotechnology Cont. • Food Science: • Faster growing salmon • Development of hybrid foods • Ex. Broccoflower, a cross between broccoli & cauliflower. • Ex. Pluot, a cross between a plum & an apricot.
Careers in Biotechnology • Farming • Researchers • Medical field • Chemists • Genetic Engineers • Forensic scientists
Careers in Biotechnology Cont. • Bioinformatics: giant computer database that stores and organizes genetic information, making it available to biotechnologists. • Input of this information is done by computer scientists.
Ethical Issues of Biotechnology • Ethics: morals, beliefs or values of an individual. • Some people believe that the science of biotechnology is unethical. • “Playing God” • Cloning • Genetic Modification/Designer babies • Stem cell Research
Ethical Issues Cont. • Risks of this science: • How will genetically altered food effect our long term health? • How will genetic modifications effect allergens in food? • Environmental issues for newly introduced seeds.
