A comparative study of DNA interaction with different counterions in solution has been conducted by the following methods: flow birefringence (FB), low‐gradient viscometry, circular dichroism (CD), and UV‐spectroscopy. The influence of counterions on the persistence length and polyelectrolyte swelling of DNA has been investigated. The process of DNA packing during the interaction with trivalent ions in solution has been studied, as well as the influence of Mn 2+ on the binding of trivalent ions with DNA.
