Analysis of transcripts isolated from gene-poor regions on bovine chromosome 6 (BTA6) by exon trapping. A: Assignment of exon trapping sequences (ETS) to the bovine genome assembly Btau4.0. B: Sequence similarity of ETS to genome sequence assemblies from human and mice. C: Distribution of ETS to the annotated bovine genome. D: Expression of ETS analyzed in a multi-tissue panel of a lactating cow.
