What is it that forms the basis of DNA fingerprinting?
What is it that forms the basis of DNA fingerprinting?
The relative proportions of purines and pyrimidines in DNA
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 occurring as highly repeated short DNA segments
Solution
DNA fingerprint is individual specific DNA identification which is made possible by the finding that no two people are likely to have the same number of copies of repetitive DNA sequences of regions. The chromosomes of every human cells contain short, highly repeated DNA sequence (15 nucleotide) called minisatellite scatterd throughout.
