Distribution of IGC in Biological vs. Synthetic Motifs. For both prokaryotic and eukaryotic motifs (top and bottom row, resp.), observed IGC is plotted on Y-axis against mean sampled IGC given IC on X-axis under MaxEnt and TU distributions (left and right columns, resp.) Colors and markers denote motif structure (dark circle: inverted repeat; medium cross: direct repeat; light triangle: monomer). The identity function y=x is plotted as a dashed line to guide the eye, and the axes have been truncated as an aid to legibility
