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
