Figure 3From: A stitch in time: Efficient computation of genomic DNA melting bubblesThe set G = P x × P y of all grid frames plotted in the xy -plane. The grid frames are colored to distinguish those that are above the diagonal (green), crossing the diagonal (red), and below the diagonal (grey), thus illustrating the subsets Ga, Gc and Gb, respectively. Frames with side lengths below 20 bp are not shown to unclutter the figure.Back to article page
