Figure 1From: Gain and loss of an intron in a protein-coding gene in Archaea: the case of an archaeal RNA pseudouridine synthase geneSecondary structures of (putative) exon-intron boundaries of crenarchaeal cbf5 newly identified in this study. The structures were predicted with mfold [10, 11]. In the cases of Staphylothermus hellenicus and Ignisphaera aggregans, manually modified structures are also shown. The predicted exons and introns are shown in upper and lower cases, respectively.Back to article page
