Biological RNA architectures are composed of autonomously folding modules which can be tailored as building blocks for the construction of RNA nanostructures. Designed base pair interactions allow complex nano-objects to self-assemble from simple RNA motifs. X-ray crystallography plays an important role in both the design and analysis of such RNA nanostructures. Here, we describe methods for the design and X-ray crystallographic structure analysis of an RNA square and two different triangles, which self-assemble from short oligonucleotides and serve as a platform for building functional nano-sized nucleic acid architectures.
