Random and natural non-coding RNA have similar structural motif patterns but can be distinguished by bulge, loop, and bond counts

The paper compares structural motifs of natural and random RNA, finding they are similar but can be distinguished by bulge, loop, and bond counts, with high classification accuracy using these features.

Phenotype bias determines how RNA structures occupy the morphospace of all possible shapes

The paper shows that RNA secondary structure morphospace is dominated by phenotype bias, not natural selection, as frequent structures are more likely to appear from random mutations.
