Title: Biotechnology - Theory and Application


1
Biotechnology - Theory and Application
2
Biotechnology
  • The manipulation of bio chemicals, mostly DNA and
    Proteins
  • Based on new techniques, developed over the last
    25-30 years
  • Has both a scientific and Economic/Business
    meaning

3
Biotechnology - Theory and Techniques
  • How/why does it work?
  • All organisms on Earth have DNA and all DNA works
    the same.
  • All DNA provides instructions to produce proteins
    that are made of Amino Acids.

4
Biotechnology - Theory
  • Biotechnology works by manipulating DNA

Cut into pieces at known locations
Recombine with other DNA pieces
Separate by size
5
Biotechnology - Applications
  • Genetic Sequencing
  • Crime scene/forensic work
  • Genetic screening
  • Human genome project
  • Evolutionary analysis

6
Biotechnology - Applications
  • Recombinant DNA technology
  • Cloning
  • Genetic engineering
  • Genetically modified organisms

7
Biotechnology - Techniques
  • Gel Electrophoresis
  • separates molecular fragments by size

8
Biotechnology - Techniques
  • Recombinant DNA
  • combines DNA from different organisms

9
Biotechnology - Techniques
  • PCR (polymerase chain reaction)
  • produces lots of DNA from a small original amount
