Abstract

DNA fingerprinting, a revolutionary technique in molecular biology, has transformed the fields of forensic science, paternity testing, and genetic research since its inception. This review explores the principles, methodologies, and applications of DNA fingerprinting, highlighting its significance in identifying individuals based on unique genetic patterns. The technique primarily relies on analyzing variable number tandem repeats (VNTRs) and short tandem repeats (STRs), which exhibit high polymorphism among individuals. Advances in polymerase chain reaction (PCR) and capillary electrophoresis have enhanced the accuracy, sensitivity, and efficiency of DNA profiling. In forensics, DNA fingerprinting has become indispensable for solving crimes, exonerating the innocent, and identifying victims of mass disasters. In medicine, it aids in diagnosing genetic disorders and establishing familial relationships. Despite its widespread utility, challenges such as ethical concerns, data privacy, and technical limitations persist. Emerging technologies, including next-generation sequencing (NGS) and CRISPR-based systems, promise to further refine DNA fingerprinting, expanding its applications in personalized medicine and biodiversity conservation. This review underscores the transformative impact of DNA fingerprinting while addressing its limitations and future prospects.
