AIM:

Genetic Engineering:

changing the
DNA of living organisms.

1. Inserting genes into other
organisms

2. Selective Breeding

3. Cloning

Transgenic organism
-

genes from
more than one species


Example: GFP mice, silk goats

First, we must ISOLATE the gene


Restriction
enzymes
: cut
DNA at specific
sequences of
nucleotides


EcoRI cuts at
“sticky end”











Separating DNA


Gel electrophoresis

can be used to
separate DNA sequences

Applications of Transgenic Organisms


Bacteria can produce insulin






Plasmid contains antibiotic
resistance= genetic marker

2. Selective Breeding

3. Cloning

Summary:


Explain the role of restriction enzymes and
plasmids in genetic engineering



How could genetic engineering be used to
treat medical conditions?
