• Set up this chart in your lab journal:
Researcher Goal of their work
1. Dr. Sabeti

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.

9. Hybrid
• Cross between two
different species
• Example: mule from
donkey and horse

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.”

13. Crop Yield
• Biotechnology improves
the crop yield.
• Measure of how many
crops are produced.

14. Ethics
• Ethical Questions – deal
with morally right or
wrong issues.
• Examples: Cloning;
Genetic Modification.

15. Cloning • Produces an organism
that is an exact genetic
copy of another.

17. Bioremediation
• Uses existing bacteria in
the soil to clean up the
environment.
• Examples: oil spills,
toxic waste.
