Abstract

Wormlike 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.

Key words： worm-like chain; free-rotation chain; mean square end-to-end distance; correction
