Preferences and occurrences in coding and intronic DNA vs. in non-genic DNA.The correlation between motif preferences and occurrences (left, right) in non-genic DNA (horizontal axis) vs. those in coding and intronic DNA (vertical axis, empty and solid circles). Pluses on the top right are for across-codon motif occurrences (23/1+3/12; vertical axis) and, in the bottom plots, for the dinucleotide occurrences in human spleen cells tabulated in Setlov (1976; left, vertical axis) and for the corresponding chi values derived from Setlov's dinucleotide occurrences (right, vertical axis).
