Abstract
A comparative study of DNA interaction with different counterions in soluti on has been conducted by the following methods: flow birefringence (FB), lo w-gradient viscometry, circular dichroism (CD), and UV-spectroscopy. The in fluence of counterions on the persistence length and polyelectrolyte swelli ng of DNA has been investigated. The process of DNA packing during the inte raction with trivalent ions in solution has been studied, as well as the in fluence of Mn2+ on the binding of trivalent ions with DNA.
