Figure 3From: Evolution of conserved secondary structures and their function in transcriptional regulation networksDAFs are lower for SNPs in the stems than in the loops/bulges of CSSs. Derived allele frequencies (DAFs) were calculated for predicted stems and loops/bulges and grouped in frequency bins of width 0.1 for four HapMap populations: A: CEU; B: YRI; C: JPT; D: CHB. Black and gray bars represent data for SNPs on stems and on loops/bulges of CSSs.Back to article page
