The structure of an RNA dodecamer shows how tandem U-U base pairs increase the range of stable RNA structures and the diversity of recognition sites. 
Structure, 4, pp. 917 - 930, 1996.

Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 1

Cell Constants:

a = 29.44   b = 28.91   c = 46.46 (Ångstroms)

α = 98.87   β = 72.95   γ = 96.16 (degrees)

Refinement:

The structure was refined using the X-PLOR program. The R value is 0.191 for 5142 reflections in the resolution range 8.0 to 2.4 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
