IR-Alupairs are defined as pairs of inverted repeatAluelements located within the indicated distance of each other (seeSTAR Methods). Distances are given in bp. Boxplots show the IR-Alupairs numbers and density on genes expressed in the cells (all) and genes with intron enrichment in DHX9 SGs (SG). Center line: median; box limits: 25th to 75th percentiles; whiskers: min to max. Significance was scored by the Poisson test.∗∗∗∗p < 10−15. See alsoFigure S6andVideos S3andS4.
