Do Now:

What is being described by


this picture?

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

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

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
