I. Introduction
Human DNA(Deoxyribonucleic Acid), is the fundamental genetic blueprint of the person. It is hereditary and responsible for the characteristics of the person.[1] The advanced biotechnology enabling the study & exploration of DNA has fundamentally revolutionized the world. DNA today can be modified[2], engineered[3], patented[4] and fingerprinted[5]. DNA Fingerprinting is one of the most revolutionized techniques to analyse DNA of individuals.[6] DNA fingerprinting (DNA Profiling /Typing /Testing)[7] is a form of DNA forensic technology that is used to identify persons by analysing the unique patterns within their DNA.[8] About 99.9% of DNA of two individuals is the same[9], however, 0.1% of DNA is unique to every individual, which results in all forms of variations in physical appearances among individuals[10] and makes DNA of every individual distinct, with exceptions to identical twins[11].
