What is Biotechnology? The science that manipulates living matter to improve the human condition or environment. Specifically: The manipulation of matters’ genes.
3
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.
4
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: 1 st mice to be successfully cloned
5
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.
6
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.
7
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.
8
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
10
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.
11
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
12
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.
