In Virology, the polymerase chain reaction (PCR) technique is widely utilized for the detection of viral nucleic acids from both RNA and DNA viruses. Specific PCR assays, such as reverse transcription PCR (RT-PCR) for RNA viruses and conventional PCR for DNA viruses, are employed to amplify target sequences of viral genomes. Key considerations in designing and conducting PCR-based assays include primer design to target conserved regions of viral genomes, optimization of PCR conditions for sensitivity and specificity, and validation of assay performance using positive and negative controls. Additionally, appropriate biosafety measures should be implemented to prevent contamination and ensure the safety of laboratory personnel when handling potentially infectious viral samples.
