Individual information distributions are sensitive to intron length. Individual information was computed at nucleotide positions -8 to +12 of donor sites flanking introns with lengths 56 to 63 (blue) or 8,192 to 16,383 (red) based on a reference set consisting of introns with lengths 8,192 to 16,383. The mean of the distribution of scores for introns 8,192 to 16,383 (10.01 ± 3.00; n = 367) is significantly higher than for introns 56 to 63 (7.57 ± 3.36; n = 6951) (p < 0.01 by one-tailed t test).
