Prediction and diversity of tracrRNAs from type II CRISPR-Cas systems.

abstract：:A very conserved pseudoknot structure has been shown to fold in influenza virus RNA. The pseudoknot encompasses the 3' splice site of segment 8 RNA in both influenza A and B viruses. By sequence comparison of influenza virus strains, we derive a consensus motif that defines a novel RNA pseudoknot family. The orientati...
