Construction and application of national forensic DNA database

1985, the British geneticist Jeff Reiss first applied DNA fingerprinting technology to identify an immigration dispute case. In the same year, PCR technology was founded, which opened the prelude to the rapid development of DNA analysis technology. With the continuous discovery of various new technologies derived from PCR and new DNA genetic markers, DNA analysis technology is constantly updated, some trace, corrupt and even polluted samples can be quickly identified, and the utilization rate of biological evidence on the spot is greatly improved, which has become a powerful weapon for identifying crimes. Forensic DNA database perfectly combines the high individual specificity of DNA with the high efficiency of computer information analysis, which greatly expands the scope of investigation, saves case handling resources, improves work efficiency, fully shows the technical effectiveness of DNA, and embodies the powerful advantages of high-tech case solving, which has become the biggest breakthrough since the application of fingerprint technology in the 20th century. Beijing Institute of Genomics, Chinese Academy of Sciences, and the Physical Evidence Identification Center of the Ministry of Public Security formally signed an agreement to establish the "Collaborative Innovation Center for Forensic Genomics" and held an unveiling ceremony. Xue Yongbiao, director of Genome Research Institute, Wang Liping, deputy director, Liu Shuo, director of Material Evidence Identification Center and Ye Jian, deputy director, attended the signing ceremony.
