B-DNA stacks similarly, but compare this with Z-DNA, which behaves much differently. Essentially all helical RNA is in A form, but DNA can also be found in A form under certain conditions (particularly in RNA-DNA hybrids). The 2'-OH of ribose favors the C3'-''endo'' sugar pucker necessary for A-form geometry. The O2' is easily seen as white spheres in <scene name='72/725869/Rna_space_filling_o2prime/1'>this space fill view</scene>. | B-DNA stacks similarly, but compare this with Z-DNA, which behaves much differently.
