BIOTECHNOLOGY

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
