Physical Questions Posed by DNA Condensation

Ha, Bae-Yeun · Liu, Andrea J.

Original · EN

When multivalent salts are added to dilute DNA solution, the DNA chains condense into bundles of a well-defined size. We explore two physical problems motivated by this phenomenon: the origin of the attractive interactions between the highly-negatively charged DNA chains that cause them to concentrate into bundles, and the mechanism that provents the bundles from growing indefinitely large.
