Fingerprints, marks or marks on human hands are called tip signatures or finger prints. Identification of specific bands from highly variable regions of DNA with radioactive probes is called DNA fingerprinting. The complex process by which an individual can be distinguished from other individuals in genetic information by determining the arrangement of deoxyribonucleotides in DNA is called DNA fingerprinting. Due to variations in DNA (ATGC), every person in the world has a different fingerprint. Fingerprints are required for land registry, marriage certificate registry, biometric seam registration, school attendance confirmation, office staff attendance confirmation, any contract etc.
