Figure 13

Concentration profile of condensed but not nearly bound ions to RNA. Open squares are simulation results and solid lines are fit by Poisson Boltzmann Equation. 13.a - the distributions of Na+ ions for different ionic solutions (0.4M NaCl – red; 0.05M MgCl2 and 0.3M NaCl – green; 0.1M MgCl2 and 0.2M NaCl – blue; 0.15M MgCl2 and 0.1M NaCl – magenta0.2M MgCl2 ). 13.b the distribution of Mg+2 ions for different ionic solutions. 0.2M MgCl2 is red and the rest of the symbols follow the same order as in 13.a
