Figure 1

Graphic depiction of the status of 442 human U12 intron clusters in A) Three eutheria, B) Seven vertebrates, C) Drosphila melanogaster , and D) Ciona intestinalis. The status of each intron is described as U12 in the comparison species, or in all comparison species (blue), at least one ambiguous intron in the comparison species or all comparison species (red), U2 in the comparison species or at least one of the several comparison species (yellow), missing intron (green), or missing gene - no orthologous gene detectable (violet).
