Over the past twenty years, DNA analysis has been revolutionalized forensic science and has become a dominant tool in law enforcement. The DNA is unique for each and every person. This application is used in forensic science to identify the criminals. The DNA is isolated from the biological samples collected from the crime scene. DNA can be extracted from saliva, blood, hairs, semen or any body fluid. The various materials like cigarette, chewing gum or any material containing body fluids may contain DNA as it is used by the person. The person is then identified by various methods like STR, RFLP, and VNTR. The identification of person is done by STR and is most applied method in forensic science. As the relevance and value of DNA profiling to forensic investigations has increased, so too has the desire to generate this information from smaller amounts of DNA. Trace DNA samples may be defined as any sample which falls below recommended thresholds at any stage of the analysis, from sample detection through to profile interpretation, and cannot be defined by a precise picogram amount. In this case here our aspects associated with the collection, DNA extraction, amplification, profiling and interpretation of trace DNA samples. Many times blood grouping does not reveals any group from trace biological evidences collected from the crime scene. The analysis of short tandem repeat (STR) DNA sequences from trace quantity of DNA is of fundamental importance to forensic science to solve the difficult criminal cases.
