4. DEFINITION
• A procedure wherein
DNA extracted from a
biological sample
obtained from an
individual is analyzed
• DNA is processed to
generate a pattern for
each person that is
generally termed as a
'DNA profile'
5. TECHNIQUES
1. RFLP - Restriction Fragment
Length Polymorphism
2. PCR - Polymerase Chain
Reaction
3. STR - Short Tandem Repeats
4. Mitochondrial DNA Analysis
5. Rapid DNA ID Microchip-
Based Genetic Detectors
6. RFLP
DNA is cut into fragments by
restriction enzymes
Chops the DNA in two at every place where the
GCGC pattern occurs
