Influence of tetraalkyl ammonium ions on the structure of poly (rG-dC).poly (rG-dC): unexpected transitions among the Z, A and B conformations.

The conformation of the double-stranded, mixed ribodeoxyribo polynucleotide, poly (rG-dC).poly (rG-dC), has been examined in the presence of tetraalkyl ammonium ions. Tetramethyl ammonium ion stabilizes the "low salt" Z conformation (1) of the polymer from submillimolar to molar concentrat...
