Over the years, it was discovered, perhaps by accident, way back in 1868, by a Swiss biologist called Friedrich Meischer when he was differentiating nucleus properties in pus cells. Since then, DNA profiling has come a long way and has been used to provide due judicial process of justice in many criminal and non criminal cases.

These efforts have also met with a reasonable degree of success such that DNA fingerprinting has now come to represent a major scientific and anti-criminal breakthrough in recent times. DNA tests have also proved conclusive evidence in absolving innocent suspects who were languishing in jail accused on
