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 …
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 …

Overview: DNA cloning (article) | Khan Academy
That’s because, during a ligation, DNA fragments don’t always get “pasted” in exactly the way we intend. Instead, we must collect DNA from several colonies and see whether each one contain …
Gel electrophoresis (article) | Khan Academy
Introduction Suppose you have just done a PCR reaction, making many copies of a target DNA region. Or perhaps you’ve done some DNA cloning, trying to "paste" a gene into a circular …

DNA sequencing (video) | Biotechnology | Khan Academy
We're going to break down DNA sequencing into three different steps. The first step is you take the sample of DNA that you are interested in sequencing and you basically use PCR to amplify …
DNA cloning and recombinant DNA (video) | Khan Academy
If we can make copied of a fragment of DNA through PCR, why do we still need DNA cloning?
