#25 — Phenol extraction of DNA is a commonly used method for removing proteins from nucleic acids; for example, to remove proteins from cell lysate during genomic DNA preparation. It's commonly used, but not well understood. Listen to this episode to get a quick explanation of how phenol extraction of DNA works.
