DNA sequence composition. Nucleotide distribution from positions −100 to 100 with respect to a poly(a) hexamer. a The nucleotide distribution for the genomic DNA sequences in the PAS-strong category. b The nucleotide distribution for the genomic DNA in the PAS-weak category. c The nucleotide distribution for sequences containing pseudo-PAS. PAS hexamers were removed from the sequence analysis
