The application of DNA profiling in the criminal justice system is an important issue in criminal investigators today. The technology is changing rapidly and several new techniques are becoming available. DNA profiling has been described as a powerful breakthrough in forensic science. The Forensic Use of DNA Profiling is a major contribution to a technology which can help not only in including the culprit but also to exclude the innocent. In this article an attempt is made to elaborate the changing scenario of the technology in the recent years as well as to present the some real cases where different variants of the DNA fingerprinting technology were successfully applied in solving the criminal cases in our laboratory.
