Applications of Genetic Engineering
Ms. Glasgow
Adapted from Byrum, Thompson, Sauer
Transgenic Tobacco
Has glowing gene from firefly
Transgenic Organisms
• Transgenic Organism: an organism that has genes from another species.– They may also be called Genetically
Modified Organisms (GMOs).
• Biotechnology: the genetic manipulation of living organisms to produce useful commercial products.
Transgenic Organisms are Used in:
1. INDUSTRY2. MEDICINE3. AGRICULTURE
TRANSGENIC BACTERIAINDUSTRIAL USES
-Break down oil from an oil spillMEDICINAL USES
-Produce hormones such as growth hormone, insulin, and clotting factor cheaply and quickly. -Help treat human diseases. (ie. diabetes)
AGRICULTURAL USES-Increase rate of nitrogen fixation in the soil
TRANSGENIC PLANTS
• Can be designed to:-grow faster-produce more fruit-be more disease resistant-be more pest resistant-be more drought or freeze resistant-have more vitamins to help nourish
people in poverty.
GM CropsGMOs are already extremely prevalent in the agriculture industry.
GM soy, corn, cotton, and colza represent more than 99% of commercial crops in the United States.
(Le Curieux-Belfond, 2009).
TRANSGENIC ANIMALS
• Can be designed to:-grow faster -grow bigger / with leaner meat-be resistant to bacterial infections-produce human proteins in their milk-study human diseases
Transgenic Salmon
GM = Genetically Modifiedvideo
What are the risks of Genetically Modified Organisms?
Could GM plants cause more allergy problems?
Unforeseen human health risksReduced genetic diversity in field
cropsLarge scale decimation of crops by
diseaseCould contaminate wild relativesNutritional value could decrease
The GMO Debate: It’s a Global Issue
Should GM foods be labeled?
