Distribution of enriched GO terms in RNA categories that anneal with targeted mRNAs GO enrichment analysis of each category (lncRNAs (A), mRNAs (B) and introns (C)) was performed, yielding a list of overrepresented terms. The corresponding genes identified as relevant to the category terms were counted, and the assembled main terms were represented as the percentages of the total genes in circular diagrams. For each list, information on the minimal FRD and p-values found through GO enrichment analysis as well as the number of GO terms found for each class is shown in (D). The main class of RNAs, introns, was also analysed as the target.
