Figure 3From: Complex organizational structure of the genome revealed by genome-wide analysis of single and alternative promoters in Drosophila melanogasterSequence similarity of neighboring genes and their promoters. (A) The gene sequence similarity of neighboring unique gene pairs whose motifs are similar (black bars) or different (white bars). (B) The promoter sequence (-130 to +50 bp) similarity of neighboring unique gene pairs whose motifs are similar (black bars) or different (white bars).Back to article page
