Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required.

Starting in the mid 1970s, scientific advances allowed the use of DNA as a material for the identification of an individual. The first patent covering the direct use of DNA variation for forensics (US5593832A [6] [7]) was filed by Jeffrey Glassberg in 1983, based upon work he had done while at Rockefeller University in the United States in 1981.
The US government's own Combined DNA Index System (CODIS) database is composed of forensic evidence assessable to local, state, and federal law enforcement officials. This database consists of genetic profiles of approximately 18 million different people, however these are limited to DNA samples from convicted felons and arrestees. [26]
The DNA patterns in fingerprint, saliva, hair follicles, and other bodily fluids uniquely separate each living organism from another, making it an invaluable tool in the field of forensic science. The process of DNA testing involves detecting specific genomes in a DNA strand to produce a unique and individualized pattern, which can be used to ...
Advancements in DNA technology and a surge of public interest are rekindling hope for breakthroughs in the long-unsolved murder of 6-year-old JonBenet Ramsey, a case that has remained a haunting ...
[2] [3] Those who specialize in forensic identification continue to make headway with new discoveries and technological advances to make convictions more accurate. [4] [5] Body identification is a subfield of forensics concerned with identifying someone from their remains, usually from fingerprint analysis, dental analysis, or DNA analysis.
Newly tested DNA evidence from the 1997 killing of a 70-year-old Pennsylvania woman indicates she was sexually assaulted and fatally beaten by an unknown man – and not by the three men who have ...
Forensic biology is the application of biological principles and techniques in the investigation of criminal and civil cases. [1] [2] Forensic biology is primarily concerned with analyzing biological and serological evidence in order to obtain a DNA profile, which aids law enforcement in the identification of potential suspects or unidentified remains.
