  2. Polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Polymerase_chain_reaction

    A strip of eight PCR tubes, each containing a 100 μL reaction mixture Placing a strip of eight PCR tubes into a thermal cycler. The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study.

  3. Real-time polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Real-time_polymerase_chain...

    A real-time polymerase chain reaction (real-time PCR, or qPCR when used quantitatively) is a laboratory technique of molecular biology based on the polymerase chain reaction (PCR). It monitors the amplification of a targeted DNA molecule during the PCR (i.e., in real time), not at its end, as in conventional PCR. Real-time PCR can be used ...

  4. Variants of PCR - Wikipedia

    en.wikipedia.org/wiki/Variants_of_PCR

    The digital polymerase chain reaction simultaneously amplifies thousands of samples, each in a separate droplet within an emulsion or partition within an micro-well. Suicide PCR is typically used in paleogenetics or other studies where avoiding false positives and ensuring the specificity of the amplified fragment is the highest priority.

  5. Reverse transcription polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Reverse_transcription...

    The exponential amplification via reverse transcription polymerase chain reaction provides for a highly sensitive technique in which a very low copy number of RNA molecules can be detected. RT-PCR is widely used in the diagnosis of genetic diseases and, semiquantitatively, in the determination of the abundance of specific different RNA ...

  6. DNA extraction - Wikipedia

    en.wikipedia.org/wiki/DNA_extraction

    The purified DNA can then be used for downstream applications such as PCR, [2] sequencing, or cloning. Currently, it is a routine procedure in molecular biology or forensic analyses. This process can be done in several ways, depending on the type of the sample and the downstream application, [ 3 ] the most common methods are: mechanical ...

  7. Molecular biology - Wikipedia

    en.wikipedia.org/wiki/Molecular_biology

    Polymerase chain reaction (PCR) is an extremely versatile technique for copying DNA. ... The basic principle is that DNA fragments can be separated by applying an ...

  8. Thermal cycler - Wikipedia

    en.wikipedia.org/wiki/Thermal_cycler

    The thermal cycler (also known as a thermocycler, PCR machine or DNA amplifier) is a laboratory apparatus most commonly used to amplify segments of DNA via the polymerase chain reaction (PCR). [1] Thermal cyclers may also be used in laboratories to facilitate other temperature-sensitive reactions, including restriction enzyme digestion or rapid ...

  9. DNA replication - Wikipedia

    en.wikipedia.org/wiki/DNA_replication

    Researchers commonly replicate DNA in vitro using the polymerase chain reaction (PCR). PCR uses a pair of primers to span a target region in template DNA, and then polymerizes partner strands in each direction from these primers using a thermostable DNA polymerase. Repeating this process through multiple cycles amplifies the targeted DNA region.
