  1. Polymerase chain reaction (PCR) (article) | Khan Academy

    Key points: Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA …

  2. Polymerase chain reaction (PCR) (video) | Khan Academy

    PCR (Polymerase Chain Reaction) is a vital technique in molecular biology, enabling researchers to amplify specific DNA fragments exponentially. Essential for cloning, forensics, and medical …

  3. Molecular mechanism of DNA replication - Khan Academy

    PCR, polymerases & amplification technology products https://www.neb.com/products/pcr-polymerases-and-amplification-technologies/pcr-polymerases-and-amplification-technologies/dna-polymerase …

  4. DNA sequencing (video) | Biotechnology | Khan Academy

    We're going to break down DNA sequencing into three different steps. The first step is you take the sample of DNA that you are interested in sequencing and you basically use PCR to amplify the …

  5. DNA technology: RT-PCR analysis of POMC cDNA - Khan Academy

    Researchers studying skin cancer and melanin synthesis used reverse transcriptase polymerase chain reaction (RT-PCR) to measure how UV light exposure stimulated the production of melanin.

  6. Gel electrophoresis (article) | Khan Academy

    Introduction Suppose you have just done a PCR reaction, making many copies of a target DNA region. Or perhaps you’ve done some DNA cloning, trying to "paste" a gene into a circular DNA plasmid. …

  8. DNA cloning and recombinant DNA (video) | Khan Academy

    If we can make copied of a fragment of DNA through PCR, why do we still need DNA cloning?

  9. DNA sequencing (article) | Biotechnology | Khan Academy

    Although genomes are now typically sequenced using other methods that are faster and less expensive, Sanger sequencing is still in wide use for the sequencing of individual pieces of DNA, such as …

  10. ATP cycle and reaction coupling | Energy (article) | Khan Academy

    ATP structure, ATP hydrolysis to ADP, and reaction coupling.
