Fig. 2From: Diverse RNA interference strategies in early-branching metazoansRandfold results for endo-siRNA and piRNA clusters. Each bar represents the percentage of clusters with Randfold p-values equal to or less than the values stated on the X-axis. The more stringent the p-value cutoff, the more confidence there is that the secondary structure of the native sequence is more stable than a randomised version of itself. For each graph, the Randfold scores of either endo-siRNAs or piRNAs are compared to the Randfold scores of all clusters not annotated as endo-siRNAs or piRNAs. For each species, all available datasets were pooledBack to article page
