  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. Staggered extension process - Wikipedia

    en.wikipedia.org/wiki/Staggered_extension_process

    The staggered extension process (also referred to as StEP) is a common technique used in biotechnology and molecular biology to create new, mutated genes with qualities of one or more initial genes. The technique itself is a modified polymerase chain reaction with very short (approximately 10 seconds) cycles. In these cycles the elongation of ...

    en.wikipedia.org/wiki/Eukaryotic_DNA_replication

    Required for initiation and elongation steps of DNA replication. A part of the Mcm2-7 helicase complex. Required after pre-RC step for loading of various proteins for initiation and elongation. Cdc45-Mcm-GINS (CMG) complex: Functional DNA helicase in eukaryotic cells Cdc6: Required for assembly of Mcm2-7 complex at ORC, in conjunction with Cdt1 .

  5. 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.

  6. Reverse Transcription Loop-mediated Isothermal Amplification

    en.wikipedia.org/wiki/Reverse_Transcription_Loop...

    This cycle can be started from either the forward or backward side of the strand using the appropriate primer. Once this cycle has begun, the strand undergoes self-primed DNA synthesis during the elongation stage of the amplification process. This amplification takes place in less an hour, under isothermal conditions between 60 and 65 °C.

  7. Reverse transcription polymerase chain reaction - Wikipedia

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

    Two-step RT-PCR, as the name implies, occurs in two steps. First the reverse transcription and then the PCR. This method is more sensitive than the one-step method. Kits are also useful for two-step RT-PCR. Just as for one-step PCR, use only intact, high-quality RNA for the best results. The primer for two-step PCR does not have to be sequence ...

  9. 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 ...
