Researcher Goal of their work
1. Dr. Sabeti
2. Dr. Keasling
3. Dr. Nelson
4. Dr. Fraley
6. Biotechnology
• The use of living
organisms to solve
problems and make
useful products.
• Examples: crop plants
and farm animals; using
yeast to make bread
rise.
7. Biotechnology
• Many types of
technology that uses:
– Cells
– Proteins
– Genetics
• Other fields use
biotechnology, like
health care, agriculture,
genetics, and food
science.
8. Selective Breeding
• Breeding selected
organisms to get
offspring with certain
traits.
• Has been an important
farming practice for
many centuries.
10. Genetically Modified
• Organisms whose genes
have been changed.
• Used for:
– Making medicines
– Treating diseases
– Improve crops
Herbicide-resistant corn!
Making insulin for diabetic patients!
11. Genome
• Complete map or
sequence of an
organism’s DNA.
• Scientists identify genes
and DNA strands.
12. DNA Fingerprinting
• Scientists collect DNA at
a crime scene
(blood/hair) and match
the DNA to suspects,
because each person
has own unique DNA.
• Part of “forensic
testing.”
