  "id": "MLC-T-CHM-012727",
  "term": "Worm-like chain",
  "field": "Chemistry",
  "definition": "A polymer chain model that describes stiff or semi-flexible macromolecules, where the chain can bend but resists sharp turns. It is characterized by a persistence length, which is the length over which the chain's orientation is correlated. This model is often used for biopolymers like DNA and some synthetic polymers.",
