Figure 2From: Montmorillonite protection of an UV-irradiated hairpin ribozyme: evolution of the RNA world in a mineral environmentEffects of UV irradiation at different exposure times on ADHR1 self-cleavage efficiency. Fractions of self-cleavage products at equilibrium (FUV∞) are weighted on fractions at equilibrium calculated for the control reactions (F∞), and plotted versus times of UV exposure in minutes. Solid line, ● : self-cleavage data from UV-irradiated ADHR1 free in aqueous solution. Dotted line, ▲ : self-cleavage data from UV-irradiated ADHR1 in the presence of montmorillonite particles.Back to article page
