Fig. 2

Distribution of protomotifs coming from true positive coding-signals separated by the true reading frame of the protein-coding sequences where they accumulate. The different parts of the figure represent protomotifs accumulated in protein-coding sequences at different BLAST bit-score starting in a frame + 1, b frame + 2, c frame + 3, d frame − 1, e frame − 2, and f frame − 3. The box size is proportional to the number of protomotifs in that frame, and the exact number of protomotifs is also shown below the X-axis. The three reading frames coming from the forward strand are colored in green color, and the three coming from the reverse strand are colored in red color
