Genetic Engineering

What are some of the ways scientists use their knowledge of DNA?

Genetic Engineering: Agriculture 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.

Mistake

Transgenic An organism that has DNA of another species

Genetic Engineering

Transgenic

Green Mice: Mouse + Plant Gene

Tobacco plant + Jellyfish gene = Transgenic Plant

Transgenic DNA from the Glowing Fish The gene that makes it glow White Rabbit Glowing Rabbit

Injecting foreign DNA into a Mouse Cell

Gene Splicing Cut a segment of DNA that codes for a specific protein. For example the gene that makes the hormone insulin for 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

ProsCons Genetic Engineering

Closure What are some of the ways scientists use their knowledge of DNA?

Response: 1. Solving Crimes 2. Agriculture 3. Manufacturing medicine 4. Testing for disease

Is genetically modified food safe? What are the potential long term effects?
