ELECTRO GEL PHORESIS
Gel electrophoresis separates an individual's DNA fragments
from one another according to size.
It analyzes macromolecules and their fragments
It is used to create a "DNA Fingerprint"

Untitled Slide
Take different DNA samples and expose them to the
same restriction enzyme to cut the DNA into fragments
This creates Restriction Fragment Length Polymorphisms
These are fragments of DNA having different lengths

Untitled Slide
Then take the DNA RFLP's and load them into the agar gel
Turn on electricity
The RFLP's will separate according to length/size of fragments
Stain the gel to see the fragments
The DNA bands create a unique fingerprint of the DNA

DNA FINGERPRINTING
DNA fingerprinting is a way of identifying a specific individual,
rather than simply identifying a species or some particular trait
It is identifying a persons traits by means of DNA
