A Short Review About DNA Finger Printing and it’s Applications

Abstract

The chemical structure of everyone’s DNA is the same. The only difference between human or animal is the order of the base pairs. There are so many millions of base pairs in each person’s DNA that every person has a different sequence. DNA DNA (Deoxyribonucleic acid), the chemical basis of life that complexes with proteins to form the chromosomes. Structurally, DNA is a double helix-two thread like long strands of genetic material spiraled around each other. DNA is a pol ymer of deoxyribonucleotides composed of Base [Adenine (A), Thymine (T), Guanine (G), Cytosine (C)], Sugar and a Phosphate. The sequential arrangement of the individual nucleotides is responsible for giving uniqueness to any individual living form be it humans, animals, plants, or microbes.
