What is it that forms the basis of DNA fingerprinting?

  1. A
    Satellite DNA occurring as highly repeated short DNA segments
  2. B
    The relative proportions of purines and pyrimidines in DNA
  3. C
    The relative difference in the DNA occurrence in blood, skin and saliva
  4. D
    The relative amount of DNA in the ridges and grooves of the fingerprints

Solution & Step-by-step Explanation

DNA fingerprinting is based on the identification of specific regions of repetitive DNA called Satellite DNA, which contains variable number of tandem repeats (VNTRs) that are unique to individuals.
