  • DNA polymorphism is a condition in which one of two different but normal nucleotide sequences can exist at a particular site in DNA.
  • DNA fingerprinting is a technique of printing the DNA finger is used for comparing the nucleotide sequences of fragments of DNA from different sources. The fragments are obtained by treating the DNA with various endonucleases, enzymes that break DNA strands at specific sites.
  • Polymorphism is the basis of genetic mapping of human genome as well as of DNA fingerprinting in DNA sequence. Therefore, it is essential to understand what DNA polymorphism means in simple terms. Polymorphism is variation at genetic level. It arises due to mutations. New mutations may arise in an individual either in the germ cells or in somatic cells. Thus, it helps in DNA fingerprinting.
