What are some of the ways scientists use their knowledge of DNA?
Genetic Engineering: Agriculture Manufacturing Medicine
Genetic Engineering is the manipulation of the DNA in cells, to change hereditary traits. • It is allows scientists to put genes from one organism into another organism.
Transgenic An organism that has DNA of another species
Transgenic White Rabbit DNA from the Glowing Fish The gene that makes it glow Glowing Rabbit
Gene Splicing Cut a segment of DNA that codes for a specific protein. For example the gene that makes the hormone insulinfor people who have diabetes.
Gene is placed into Bacteria DNA Bacteria now makes insulin
Controversial WHY?
Negative Aspects • Violates the integrity of life • Unethical • Do human beings know what is best? • Puts species at risk • Does not take into account changing conditions
ClosureWhat are some of the ways scientists use their knowledge of DNA?
Response:1. Solving Crimes2. Agriculture3. Manufacturing medicine4. Testing for disease
Is genetically modified food safe?What are the potential long term effects?
