Classification of coding sequences (solid line) and introns (dashed line) of Homo sapiens (A,D,G,J), Drosophila melanogaster (B,E,H,K) and Arabidopsis thaliana (C,F,I,L) at 150 (A,B,C), 200 (D,E,F), 250 (G,H,I) and 300 bp (J,K,L) by UFM. The number on the upper left of each panel indicates the proportion of introns (%) that do not have any ORF with the purine bias of coding sequences for the size threshold considered. The sample size was 1000 in both the introns and coding sequences.
