Intron gain by DSBR. Alignment between the reverse complement of a gained intron in Dwil\GK24465 and a segment of D. wil's mitochondria (e-value = 0.032, coverage = 99%). The best score produced by randomly shuffling and realigning these sequences 1, 000 times was significantly lower (Pearson chi-square test, p < 0.05) than the score between the original sequences.
