Figure 5From: Genomic DNA from animals shows contrasting strand bias in large and small subsequencesAnalysis of exons and introns in the human genome. The graph shows correlations of (G - C) versus (A - T) by window size in a) the unmasked genome and b) the masked genome. For both subgraphs, each point is based on a sample of 4000 windows lying entirely within an intron (the blue upper line) or exon (the red lower line). The error bars show 95% confidence intervals.Back to article page
