Polymerase chain reaction (PCR) (article) | Khan Academy
Each step involves coupling, capping, and oxidation processes to ensure precision. After synthesis, primers are purified using techniques like HPLC and verified for accuracy.
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 …
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 …
Gel electrophoresis (article) | Khan Academy
For your first question: You will do PCR of the entire sample. Then a restriction enzyme is used to cut the part you want. One restriction enzyme will make the cut on the same place in all …

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 …
DNA cloning and recombinant DNA (video) | Khan Academy
After isolating that plasmid (that now has the antibiotic resistance gene), you can add the target gene through the "paste" step. When grown on antibiotic-containing media, you will select for …
