  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 …

  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. Polymerase chain reaction (PCR) (practice) | Khan Academy

    The image below depicts a target sequence that needs to be amplified using polymerase chain reaction (PCR), and the set of primers for the same. Where should the primers bind to enable …

  4. Biotechnology (practice) | Khan Academy

    A researcher used polymerase chain reaction (PCR) to test four individual diploid nematodes for the presence of a mutation in Gene Y. The researcher designed the reaction so that the DNA …

  5. Reação em cadeia da polimerase (PCR) (artigo) | Khan Academy

    Na PCR, a reação é repetida ciclicamente através de uma série de alterações de temperatura, o que possibilita a produção de muitas cópias da região de interesse. A PCR tem muitas …

  6. DNA technologies (apply) (practice) | Khan Academy

    A researcher used polymerase chain reaction (PCR) to test four individual diploid nematodes for the presence of a mutation in Gene Y. The researcher designed the reaction so that the DNA …

  7. DNA technology questions (practice) | Khan Academy

    Evidence that DNA is genetic material 1 Evidence that DNA is genetic material 2 Gel electrophoresis Polymerase chain reaction (PCR) DNA libraries & generating cDNA DNA …

  8. 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.

  9. Reacción en cadena de la polimerasa (PCR) - Khan Academy

    La PCR tiene muchas aplicaciones en la investigación y en la práctica. Se utiliza de forma rutinaria en la clonación de ADN, el diagnóstico médico y el análisis forense de ADN.

  10. 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 …
