Genetic Engineering

Is the idea that we can
use our knowledge of
genetics to create desired
outcomes.

The history of genetic
engineering


We have used selective
breeding for years to get
dogs well suited for certain
jobs (coon dogs, pit bulls,
etc.) as well as horses, cats,
etc.


Hybridization is a type of
selective breeding that
crosses two different
organisms to get the best
traits from each:


For example: a mule is a
donkey
-

horse hybrid. It
possesses good traits from each.

Using DNA structure, we
can use more precise
methods of genetic
engineering


Cloning
-

creating exact genetic
copies of an organism


Genetic screening
-

looking at
an organisms genes

Using DNA structure, we
can use more precise
methods of genetic
engineering


Gene therapy
-

when we fix or
replace genes that cause
diseases


DNA identification
-

using a
person’s unique DNA sequence
to identify them


Cloning has Potential
Risks and Benefits


Cloning technology has the
ability to help with medical
advances in organ and tissue
transplant


But also comes with ethical
risks
-

can we clone entire
people? What can we and can’t
we clone?

Genetic Screening


Has the potential to warn
people of genetic flaws
-

like
those that might cause
disease


But again comes with the
ethical debate of what we
should and shouldn’t use
genetic screening for.

Gene Therapy



Has the ability to lead to
cures for many genetic
disorders like:


Muscular Dystrophy,
Parkinson’s Disease, Lou
Gehrig’s Disease (ALS), etc.

DNA Identification:


Can be used to put criminals in
jail, determine paternity, etc.


Again this technology raises
questions: about privacy and
other ethical issues.
