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 …
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 the process:
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 by gel …
Evidence for evolution (article) | Khan Academy
These shared features suggest that all living things are descended from a common ancestor, and that this ancestor had DNA as its genetic material, used the genetic code, and expressed its genes by …
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 corretos, …
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 restriction …
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 circular piece …
