Biotechnology Notes

Key Terms

Biotechnology = the manipulation of living
organisms or parts of organisms to make
products useful to humans.

Genetically Manipulated Organism (GMO) =
Those organisms that have had genetic
material removed and/or inserted in order
to change one or more particular traits of
an organism.


Transgenic = Organism that have genetic
material inserted from a different species.

The Need for Biotechnology


Food Supply (particularly for less
-
developed
countries)



Green Revolution: increase in crop production by
crop breading, new pesticides, and new
management techniques



Genetic Make
-
up: Selecting for organisms with
highly desired traits



Genetic Improvement: Increase production at lower
cost

Current Uses


Plants: Transgenic crops that have been
modified to resist insects



Animals: Cloning, genetic sequencing



Medicine: Gene Therapy, Genetic Mapping



Environment: Bioremediation (using organisms
to fix an environmental problem)

History Lesson


Selective Breeding


Disease Prevention and Treatment


vaccines and antibiotics


Reproduction


artificial insemination


Gene Transfer


Genetic Engineering

Selective breeding


Produces organisms with desired traits


Requires time and several generations
to produce offspring with the desired
trait



Ex:


Short vs long haired cats


Milk production in cattle


Disease resistant foods
