Figure 6.

Adjacent ORF anomalies. Eight different classes of adjacent ORF anomalies are pictured schematically. Open boxes represent ORFs, and their arrows represent their orientation from translational start to stop. Dashed open boxes represent non-conserved ORFs. The solid lines indicate the transcripts detected by Virtual Northern and RACE analysis. The dashed portions of those lines represent variation in the extent of 3'-UTR overlap between different cases. The number following each title lists the number of loci in that class.
