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

    In this article, we’ll take a look at methods used for DNA sequencing. We'll focus on one well-established method, Sanger sequencing, but we'll also discuss new ("next-generation") …

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

    DNA sequencing is a method used to determine the precise order of nucleotides (adenine, thymine, cytosine, and guanine) within a DNA molecule. Here's a more detailed explanation of …

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

    Using PCR, a DNA sequence can be amplified millions or billions of times, producing enough DNA copies to be analyzed using other techniques. For instance, the DNA may be visualized …

  4. Gel electrophoresis (article) | Khan Academy

    A technique used to separate DNA fragments and other macromolecules by size and charge.

  5. Sequenciamento de DNA (artigo) | Khan Academy

    Sequenciamento de DNA é o processo de determinação da sequência de bases nucleotídicas (As, Ts, Cs, e Gs) em um pedaço de DNA. Hoje em dia, com os materiais e equipamentos …

  6. Overview: DNA cloning (article) | Khan Academy

    Key points: DNA cloning is a molecular biology technique that makes many identical copies of a piece of DNA, such as a gene. In a typical cloning experiment, a target gene is inserted into a …

  7. Human genome project (practice) | Khan Academy

    Due to the large size of DNA molecules, cutting them up into smaller molecules makes the job of reading them easier. However, these fragments are first cloned into vectors that are …

  8. Biotechnology | Biology archive | Science | Khan Academy

  9. Restriction enzymes & DNA ligase (article) | Khan Academy

    How can pieces of DNA from different sources (such as a human gene and a bacterial plasmid) be joined together to make a single DNA molecule? One common method is based on …

  10. DNA sequencing (video) - Khan Academy

    DNA sequencing is a method used to determine the precise order of nucleotides (adenine, thymine, cytosine, and guanine) within a DNA molecule. Here's a more detailed explanation of …
