AbstractWormlike chain is a popular model for biological macromolecules such as DNA, and for semi-rigid and rigid-chain polymers. This paper discusses the worm-like chain model, especially the mistake in the derivation of end-to-end distance, and suggests an effective solution using a free rotation chain model. It is helpful for using the wormlike chain model correctly.
