DNA and its Counterions: Metal Ions, Amino Acids, Histones and Protamines
The conformation of DNA is influenced both by its sequence and by the counterions and other small molecules (in particular water) which interact with it. In this article we will review the effect on DNA of counterions, including basic proteins. We will not deal with sequence effects and thus we will not consider specific protein-DNA interactions. We will also not consider the influence of ions on the denaturation of DNA in solution.
