DNA Introduction

Since the introduction of DNA testing started to use as evidence in 1990, the criminal justice system has been improved but mistakes and human errors have downplayed the effectiveness of this DNA technology. This DNA forensic has undeniably helped in solving tough cases and yet, public awareness of the information is only surface touching depth.

Forensic identification tests can link the DNA segments to each individuals existing.Examples of DNA uses in the field include identification of potential suspects whose DNA maybe match leftovers at crime scenes, establishment of paternity and family relationships of victims whom could not be recognized based on their outlooks

DNA testing

DNA testing centers provide service-oriented DNA analysis for determining biological relationships through DNA paternity testing, DNA genealogy and anthropology testing and sibling DNA testing, and other peripheral services like DNA banking and ID services and DNA detective testing services, among others.

DNA paternity testing is the most popular genetic testing service, and helps in establishing the paternity of not only a child but of an unborn fetus. Most DNA paternity tests are 99.9% accurate and can be used for legal purposes as well.

DNA Techniques

DNA testing, DNA typing or DNA profiling is one of promising techniques used to distinguish between individuals of the same species. The process uses samples of their DNA for identifying their genetics. In 1985, the process was publicly launched by Sir Alec Jeffreys at the University of Leicester. Genetic fingerprinting exploits highly variable repeating sequences called microsatellites in finding the differences between two human beings.

CONCLUSION

DNA testing centers not only provide DNA analysis and testing services such as paternity testing and DNA banking but also offer counseling for researching biological relationships. These centers process samples through accredited laboratories for determining biological relationships and giving highly accurate test results. Some of the popular DNA testing centers are GeneTree, Childsafetyaid, DNA Testing Center of America and Atlanta DNA Center Inc., among others.
