1. Biotechnology
Messana
Science 8

2. BIOTECHNOLOGY
Technology based on a biological system or living organism
Uses organisms to solve real world human problems
Medicine
Agriculture
Food processing

3. BIOENGINEER Create products that meet some human need
Research & development
Quality control
Manufacturing & production
Agriculture

4. Biotech in Medicine Genetic testing = “picture” of the DNA
Catch criminals
Determine parents of a baby
Screen for diseases/genetic abnormalities
Gene therapy = utilizes viruses or bacteria to enter cell and replace defective genes
Cloning = creation of genetically identical organisms
Dolly the Sheep
Cloning human would be very difficult, is it ethical??
Tissue culturing = grow human tissues and organs in lab
Development of better/cheaper drugs

5. Biotech in Microbiology
Making bacteria that will eat harmful pollutants
Help bacteria reproduce faster
Bacteria will clean up after an industrial accident
Bacteria will increase rate of nutrient cycling through ecosystem
Microbes used to produce food products
Control production of harmful bacteria in foods
Control microbes in water

6. Biotech in Agriculture
Increase crop yields
Transgenic crops = DNA altered by humans
Insecticide use, plants that are insect resistant
Transgenic animals = produce more, faster; products contain fewer hormones, antibiotics, cholesterol
Reducing environmental stressors
Make transgenic crops that can survive in harsh conditions
Improving food quality
Alter size, taste, amount of nutrients, when it ripens, how long it stays fresh

7. Ethical Issues
Will cross-pollination between transgenic crops & wild plants have unforeseen consequences?
How will transgenic crops affect humans long term?
Will transgenic crops affect food allergies or cause new unknown diseases?
Who gets to make decisions on Human Genome Project info?
Is it OK to pick desired genetic characteristics for a baby?
What are the effects of genetic manipulation on complex human traits?
