Figure 6. Frequency distributions of the lengths of ORFs, exons, and coding-sequence of genes from different genomes.

Figure 6

The frequency distributions of the lengths of exons and the complete coding sequence of genes and the ORFs from the genomes of H. sapiens (A), A. thaliana (B), C. elegans (C), D. melanogaster (D), P. falciparum (E), and combined fungal genomes of S. pombe and S. cerevisia (F), and the lengths of the coding sequence of genes and ORFs from the combined prokaryotic genomes of E. coli K12 and S. pneumoniae R6 (G) were plotted. Frequencies of every 100 consecutive ORF lengths were binned. The frequencies of the TCSs are shown on the left Y-axis and the frequencies of the ORFs and exons are shown on the right Y-axis. In order to magnify the frequencies within the region of non-randomness, the frequencies above certain threshold values (250 and 500 respectively for left and right Y-axes) are not shown, as the frequencies of only ORFs/exons of very short lengths exhibit such large frequencies (Figure 2).
