Figure 4.

Comparison of exon boundary locations and melting fork probability peaks. Independent analyses were carried out on left and right exon boundaries as compared to left- and right-facing melting forks, respectively. In the upper part, dashed vertical lines indicate left (L, red) and right (R, blue) exon boundaries. In the lower part, probabilities of left- and right-facing melting forks appear as red and blue peaks, respectively. The black curve shows the GC content in a 100-bp sliding window (values on right axis).
