From: Comparative genomics of Drosophila and human core promoters
The distribution of nucleotides across Drosophila and human promoters. The distribution of mononucleotides across the (a) 1,500 bp region of 10,914 Drosophila and (b) 15,011 and (c) 12,926 human promoters; the frequency of each mononucleotide is plotted against position (in 20 bp bins). The TSS occurs in bin 51 and its location is indicated. (d) The frequency of occurrence of the CA dinucleotide, at a single base-pair resolution across the 1,500 bp promoter region for all three datasets.
