Figure 1.
Empirical, smoothed empirical, and geometric intron length distributions up to 4000 nt, on a log–log scale. The smoothed empirical length distribution is very close to the distribution observed in the 3889 fully confirmed genes of WS100. The geometric distribution, in contrast, assigns far too much probability to very short introns, too little to introns of the most common lengths, too much to introns between 100 and 1000 nt, and too little to introns longer than 2000 nt.
