Characterizing 3′ ends of fish Igf2 genes by analysis of RNA-Seq libraries. A–D, mapping putative 3′ ends of fish Igf2 genes by examination of gene expression data from species-specific RNA-Seq libraries, with 60-bp genomic segments a–f or a–g as probes. A possible polyadenylation signal is underlined in the DNA sequence below each graph, and vertical arrows denote potential 3′ ends of Igf2 mRNAs. A, fugu, library SRX4020085 (liver). B, stickleback, library SRX2712198 (liver). C, cod, library SRX1044010 (liver). D, Medaka, library SRX661040 (liver).
