From: Frequency distribution of TATA Box and extension sequences on human promoters
Frequency distribution of TATAAAAG and TATATAAG on three other organisms. TATAAAAG and TATATAAG are the two TATA elements which show peak pattern of frequency distribution in human promoters. The investigation on their frequency distribution on other three organisms shows the same pattern. Figure 5(a), (b) and (c) show their frequency distribution on the gene promoters of mice, zebrafish and drosophila melanogaster respectively.
