Model SDR RNA. The RNA sequence is shown on the right, with the phosphate positions numbered. By convention each phosphate “belongs” to the ribose that is on the 3′-side of the P atom. The inset shows the detailed chemical structure of an R5 (orange) attached at position 9. Notice the deoxyribose substitution at nucleotide 8, which replaces the 2′-OH group adjacent to the labeled phosphorothioate with a 2′-H (blue).
