What is it that forms the basis of DNA Fingerprinting?
The relative difference in the DNA occurrence in blood, skin and saliva
The relative amount of DNA in the ridges and grooves of the fingerprints
Satellite DNA occurs as highly repeated short DNA segments
The relative proportions of purines and pyrimidines in DNA
DNA fingerprinting involves identifying differences in specific regions in DNA sequence called repetitive DNA. These sequences are separated from bulk genomic DNA as satellite DNA, which consists of highly repeated short DNA segments. These sequences show a high degree of polymorphism and form the basis of DNA fingerprinting , .
