GC content and TE content of lincRNAs. a GC content of lincRNAs, lincRNA introns and coding sequences. LincRNAs have an intermediate GC content: higher than introns but lower than coding sequences. b Percentage of repeats of lincRNAs. LincRNAs have also an intermediate level of repeats. More repeats than coding sequences but less than introns. c Conserved lincRNAs have less TE. In contrast lincRNAs with signals of conservation in their ORF or paralogs have more TEs
