  1. 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.

  2. 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 …

  3. 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 …

  4. Bacterial transformation & selection (article) | Khan Academy

    After a ligation, the next step is to transfer the DNA into bacteria in a process called transformation. Then, we can use antibiotic selection and DNA analysis methods to identify bacteria that contain the …

  5. Gene expression and regulation | AP®︎/College Biology | Khan …

    Examine key tools such as polymerase chain reaction (PCR), gel electrophoresis, and DNA sequencing. Discover how these methods advance research, medicine, and biotechnology applications.

  6. 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 samples. So you …

  9. Polymerase chain reaction (PCR) (practice) | Khan Academy

    The image below depicts a target sequence that needs to be amplified using polymerase chain reaction (PCR), and the set of primers for the same. Where should the primers bind to enable this reaction to …

  10. 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 the right …
