Brief Description:
PCR, or polymerase chain reaction, uses a thermostable DNA polymerase to amplify genomic sequences of living organisms via in vitro methods. Observations of PCR results can lead to information regarding genetic variances, chromosomal rearrangements, and the presence of viral pathogens (Saiki et al. 1988). PCR can also have applications in diagnostics and forensics (Leboffe & Pierce 2005).
