Figure 9.

Dependence of the persistence length P on [Mg2+]. Main panel: experimental persistence length versus [Mg2+]. Inset: dependence of the free energy of formation of the RNA hairpin Inline graphic on [Mg2+] with fixed 50 mM [Mon+] obtained using the TBI model (44,45). Black points are the values of the free energy of formation that we used for our analysis.
