Figure 1From: Adaptation of the short intergenic spacers between co-directional genes to the Shine-Dalgarno motif among prokaryote genomesDistribution of the spacing lengths. Distribution of the spacing lengths between genes in co-directional (A), convergent (B) and divergent (C) orientations. A representation for each transcriptional orientation is shown. A distribution of the short spacing lengths between co-directional genes is shown in detail (A).Back to article page
