Figure 2From: Human Pol II promoter recognition based on primary sequences and free energy of dinucleotidesThe four kinds of fractal curves for the promoter, exon and intron sequences. The figures show that there are some differences between the promoter and non-promoter (exon/intron) sequences, which suggests that it's possible to extract some values from them to distinguish the promoter sequences from the non-promoter sequences.Back to article page
