  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.

    en.wikipedia.org/wiki/Molecular_biology

    Polymerase chain reaction (PCR) is an extremely versatile technique for copying DNA. In brief, PCR allows a specific DNA sequence to be copied or modified in predetermined ways. The reaction is extremely powerful and under perfect conditions could amplify one DNA molecule to become 1.07 billion molecules in less than two hours.

  4. Polymerase cycling assembly - Wikipedia

    en.wikipedia.org/wiki/Polymerase_cycling_assembly

    Polymerase cycling assembly (or PCA, also known as Assembly PCR) is a method for the assembly of large DNA oligonucleotides from shorter fragments. The process uses the same technology as PCR, but takes advantage of DNA hybridization and annealing as well as DNA polymerase to amplify a complete sequence of DNA in a precise order based on the single stranded oligonucleotides used in the process.

  5. Gene amplification - Wikipedia

    en.wikipedia.org/wiki/Gene_amplification

    Polymerase chain reaction, an easy, cheap, and reliable way to repeatedly replicate a focused segment of DNA by polymerizing nucleotides, a concept which is applicable to numerous fields in modern biology and related sciences. [2] Ligase chain reaction, a method that amplifies the nucleic acid used as the probe.

  6. DNA sequencing - Wikipedia

    en.wikipedia.org/wiki/DNA_sequencing

    A polymerase chain reaction (PCR) then coats each bead with clonal copies of the DNA molecule followed by immobilization for later sequencing. Emulsion PCR is used in the methods developed by Marguilis et al. (commercialized by 454 Life Sciences ), Shendure and Porreca et al. (also known as " polony sequencing ") and SOLiD sequencing ...

  7. Variants of PCR - Wikipedia

    en.wikipedia.org/wiki/Variants_of_PCR

    InterSequence-Specific PCR (or ISSR-PCR) is method for DNA fingerprinting that uses primers selected from segments repeated throughout a genome to produce a unique fingerprint of amplified product lengths. [16] The use of primers from a commonly repeated segment is called Alu-PCR, and can help amplify sequences adjacent (or between) these repeats.

  8. Digital polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Digital_polymerase_chain...

    Chip-based Digital PCR (dPCR) is also a method of dPCR in which the reaction mix (also when used in qPCR) is divided into ~10,000 to ~45,000 partitions on a chip, then amplified using an endpoint PCR thermocycling machine, and is read using a high-powered camera reader with fluorescence filter (HEX, FAM, Cy5, Cy5.5 and Texas Red) for all ...

  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.
