Genetic Fingerprinting

Understand the concept of a Variable Number Tandem Repeat (VNTR)
VNTR is crucial in answering questions on genetic fingerprinting
VNTR is often associated with Polymerase Chain Reaction (PCR)
Need to explain biological principles of genetic fingerprinting techniques
Should be able to interpret data from gel electrophoresis used to separate DNA fragments
Explain why genetic fingerprinting might be used in forensic science, medical diagnosis, animal and plant breeding.
