Figure 7
Spatial distribution of poly dA.dT tracts in proximal flanking intergenic regions of three Plasmodium spp. The schematics represent the distribution (bin size of 50 bases) of homopolymer tracts of N = 5, 10, 15 and 20 bases (see key for base and size of tract) in the sense-strand of proximal upstream and downstream intergenic sequences. Distance from the open reading frame (ORF) is represented on the X-axis. The frequency of each tract (Fobs) is represented on the Y-axis. The scale for distance and Fobs is represented in the key.
