  3. 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") …

  4. DNA structure (article) | Khan Academy

    Learn about complementary nucleotide base-pairing and antiparallel strands in the DNA double helix.

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

    How the sequence of nucleotide bases (As, Ts, Cs, and Gs) in a piece of DNA is determined.

  6. DNA replication (article) | Khan Academy

    During DNA replication, the two strands of the DNA double helix are unwound and separated by enzymes. Each strand then serves as a template, or guide, for synthesizing a new, …

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

    Introduction to genetic engineering Intro to biotechnology DNA cloning and recombinant DNA Overview: DNA cloning Polymerase chain reaction (PCR) Polymerase chain reaction (PCR) …

  8. Leading and lagging strands in DNA replication - Khan Academy

    DNA replication is a precise process where DNA unwinds and splits into two strands. Each strand then serves as a template for a new DNA molecule. The leading strand is built continuously, …

  9. Gel electrophoresis (article) | Khan Academy

    Using electrophoresis, we can see how many different DNA fragments are present in a sample and how large they are relative to one another. We can also determine the absolute size of a …

  10. 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 …
