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.16 pages, 1 figure, to appear in "Physical Chemistry of Polyelectrolytes," ed.
