Abstract

Forensic serology and DNA profiling are extremely important branches of forensic science. Forensic serology has been a major area of forensic science biology for many decades. Forensic serology is mainly related with the identification of biological evidence. DNA as a newer technology in forensic science evidence examination is the most beneficial and an important part as compared to the forensic serology division. In the biology laboratory, forensic biologists performs mainly serological and DNA analysis of fluids. Forensic techniques for DNA profiling which being developing around 1985 have replaced the classical or traditional genetic system previously used such that forensic serology. DNA typing can help to bring home the guilt, acquit the innocent those wrongly convicted. In this article we’ll review two techniques of forensic science which are the basis of forensic serology and DNA typing as important forensic evidence. Apart from all available techniques DNA profiling for evidence easily give the result. DNA profiling is specially used against serious crime and criminals. The recent advancements of DNA technologies are certainly helpful in the conviction. DNA analysis is the most effective way to solve any case easily. When any crime is occurring, people can leave evidence at the crime scene and they leave a trace such as biological materials that contain DNA. As compose to serology and biology examination of all body fluids and other relative evidence examination are tough because of the evidence isolation and preserved but in DNA profiling, all preserving integrity of DNA for a long period and storage of DNA becomes easy. Apart from all available techniques DNA profiling for evidence easily give the result. DNA profiling is used in most of the cases nowadays to solve serious crime offences.
