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