Figure 3.
Frequency of dinucleotides used as TSSs. The frequencies of 16 dinucleotides at the −1,0 position, where the zero position represents the representative TSS, were examined in non-RP gene promoters. Each bar represents the percentage of each dinucleotide. The percentage of each dinucleotide in the genome sequence is also shown. To examine which dinucleotides were used as TSSs in each promoter class, we compared the percentage of each dinucleotide in each promoter class and the genome, and we evaluated the difference using the binomial test. (*) P < 0.05 and (**) P < 0.01, Bonferroni-corrected.
