  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") methods that have …

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

    DNA sequencing involves three main steps: 1) using PCR to amplify DNA fragments, 2) introducing dideoxynucleotides that halt DNA strand elongation, and 3) employing a computer to analyze the …
