DNA test--a forensic boon.

DNA fingerprinting (DNAFP) profiles can be applied to identify an individual in criminal as well as in civil cases. The main advantage of the technique is its ability to analyse small and environmentally challenged samples and to accurately establish their origins with a high degree of certainty: DNAFP can identify an individual in criminal and civil cases eg, rape, kidnapping, assassination and so on. The forensic DNA analysis can be stored in a data bank. It can help in crime prevention by giving the information of potential criminals. Reliability of DNA technique is very important. In paternity and maternity identification, when called for, DNA testing plays very much positive role.
