Polymerase chain reaction itself is the process used to amplify DNA samples, via a temperature-mediated DNA polymerase.The products can be used for sequencing or analysis, and this process is a key part of many genetics research laboratories, along with uses in DNA fingerprinting for forensics and other human genetic cases.

Similarly, thermal asymmetric interlaced PCR (or TAIL-PCR) is used to isolate unknown sequences flanking a known area of the genome. Within the known sequence, TAIL-PCR uses a nested pair of primers with differing annealing temperatures. A 'degenerate' primer is used to amplify in the other direction from the unknown sequence.

Second, the formerly obtained PCR products are combined together into the overlap extension PCR reaction, where the complementary overhangs bind pair-wise allowing the polymerase to extend the DNA strand. Eventually, outer primers targeting the external overhangs are used and the desired DNA product is amplified in the final PCR reaction.
By incorporating high throughput sequencing adaptors into the PCR primers, PCR products can be sequenced with massively parallel sequencing. Alternatively, and labour-intensively, PCR product can be cloned and sequenced. Nested PCR methods can be used to enhance the product for sequencing.

The polymerase chain reaction (PCR) is a commonly used molecular biology tool for amplifying DNA, and various techniques for PCR optimization which have been developed by molecular biologists to improve PCR performance and minimize failure.
This technique makes many copies of the virus genome using virus-specific probes. Variations of PCR such as nested reverse transcriptase PCR and real time PCR can also be used to determine viral loads in patient serum. This is often used to monitor treatment success in HIV cases.
