Forensic dna analysis has played a crucial role in the investigation and resolution of thousands of crimes since the late 1980s the demand for tools and technologies in all areas of forensic science, including dna testing, far. Dna analysis is the process in which genetic sequences are studied it is used by law enforcement and medical personnel to identify a particular person or species, and even specific cancers and diseases at one point the analysis process was very limited. Dna fingerprinting is important for forensic science in helping to solve crimes by exonerating some suspects and helping to identify and convict the guilty person.

The forensic technique is becoming ever more common—and ever less reliable. Forensic science technicians aid criminal investigations by collecting such as forensic biologists and they also may use computers to examine dna. Forensic dna learn all about this fascinating area of forensic science. While current technologies being used in the field of forensics are effective and efficient, next-generation sequencing is capable of ushering in a new era of dna. To identify individuals, forensic scientists scan 13 dna regions that vary from person to person and use the data to create a dna profile of that individual (sometimes called a.
