  • Virus detection and identification using random

    2007-6-28 · PCR-based detection and identification of viruses assumes a known, relatively stable genome. Unfortunately, high mutation rates may lead to extensive changes in viral nucleic acid sequences making dedicated PCR primer use problematic. Furthermore, in bioterrorism, viral consensus sequences can be genetically modified as a countermeasure to RT-PCR and DNA chip detection.

  • Polymerase Chain Reaction (PCR) Fact Sheet

    2021-4-21 · Sometimes called 'molecular photocopying,' the polymerase chain reaction (PCR) is a fast and inexpensive technique used to 'amplify' - copy - small segments of DNA. Because significant amounts of a sample of DNA are necessary for molecular and genetic analyses, studies of isolated pieces of DNA are nearly impossible without PCR amplification.
