Abstract
Polymerase Chain Reaction (PCR) techniques have revolutionized forensic DNA analysis, enabling the precise amplification of trace DNA samples. This abstract provides a concise overview of the pivotal role of PCR in forensic science. It delves into the principles of PCR, emphasizing its ability to amplify specific DNA sequences with remarkable sensitivity and specificity. Multiplex PCR, a variant technique, allows for simultaneous amplification of multiple genetic loci, enhancing the efficiency of forensic investigations. This abstract further highlights the broad applications of PCR in criminal investigations, paternity testing, and disaster victim identification. Recent advancements, such as MiniSTRs and Next-Generation Sequencing (NGS), are elucidated for their crucial contributions in addressing challenging forensic scenarios. Despite its instrumental role, PCR-based DNA analysis is not without challenges, with considerations including DNA contamination and low-template samples. The abstract concludes with aforward-looking perspective on the emerging field of forensic epigenetics and metagenomic analysis, offering a glimpse into the promising future of PCR techniques in forensic DNA analysis. PCR stands as an indispensable tool in modern forensic science, unraveling genetic identities from the most minute of genetic traces.
