To learn more about an RNA, please click on its dual graph.

These graphs have been ordered according to the number of vertices they each contain and according to the second smallest eigenvalue of their Laplacian matrix ( is given).

**Please Note: Red graphs denote those structures found in Nature and black graphs denote those that have either not yet been found or do not exist (a question mark is placed for these in the lower right corner).  Blue graphs represent candidate RNA motifs (which have not yet been found in Nature).  V stands for number of vertices, and N_v stands for the number of possible RNA topologies for V number of vertices.

*Number of possible RNA topologies (with an asterisk) has been enumerated using a probabilistic method.
