Genetic Engineering

1
Genetic Engineering

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

2
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.

3
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.

4
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

5
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 persons unique DNA
  sequence to identify them

6
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 cant we clone?

7
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 shouldnt use genetic screening for.

8
Gene Therapy

• Has the ability to lead to cures for many genetic
  disorders like
• Muscular Dystrophy, Parkinsons Disease, Lou
  Gehrigs Disease (ALS), etc.

9
DNA Identification

• Can be used to put criminals in jail, determine
  paternity, etc.
• Again this technology raises questions about
  privacy and other ethical issues.
