Optimal Target Search on a Fast-Folding Polymer Chain with Volume Exchange

Research output: Contribution to journalArticle

Abstract

We study the search process of a target on a rapidly folding polymer (“DNA”) by an ensemble of particles (“proteins”), whose search combines 1D diffusion along the chain, Lévy type diffusion mediated by chain looping, and volume exchange. A rich behavior of the search process is obtained with respect to the physical parameters, in particular, for the optimal search.
