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.

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

Bacterianow

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

Pros Cons

Genetic Engineering

Closure What 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?
