Genetic Engineering
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
Genetic Engineering

DNA from the Glowing Fish
The gene that makes it glow

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
