Transcript and Presenter's Notes

Title: Biotechnology


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?
