Figure 7From: Ab initio identification of human microRNAs based on structure motifsFrequency distribution (in percent) of expression-sequence matches over the window positions. 100 nt windows centered around all 474 known human miRNAs and all 117 unknown predicted miRNAs. Only regular expressions that match mostly positive structures are used. Loop region (approximately central) and flanking regions are less matched than stem sequences.Back to article page
