DNA Barcode Technology and Its Application Prospects in Forensic Medicine

Traditional species identification has gone through five stages -- morphology, cytology, biochemistry, immunology and molecular biology. At present, the use of DNA technology for species identification has become a research hotspot. In the use of DNA for species identification, the presentation and application of DNA barcode is of epoch-making significance. With the successful application of new technology in species identification, forensic species identification has also made corresponding development, and is expected to play an important role in forensic related fields. This paper briefly describes the general situation and principles of DNA barcode technology as well as its advantages and limitations when applied to biological classification, and discusses the future significance and feasibility of DNA barcode technology in forensic applications, in order to provide new ideas for future forensic identification.
