DNA-Encoded Chromatin Structural Intron Boundary Signals Identify Conserved Genes with Common Function

Figure 4

Dinucleotide counts at intron-exon boundary. The dinucleotide counts for the region −40 to +10 nucleotides from the upstream boundary between intron and exon as indicated at the bottom of the figure. Solid black bar indicates the counts for exons containing the U − 26 signal. Grey bars represent 5 random samples of similar size for comparison.
