Intron-Exon structure of Group II Nme genes in chordates. Intron-Exon structure of Nme5 (A), Nme6 (B), Nme7 (C), Nme8/NME9 (D), and Nme10 (E) genes structure among chordates. Intron-exon structure was obtained using Ensembl database, or, when no information was available, by Blat of protein and cDNA sequences on genomes assemblies. Boxes correspond to exons. Non-coding exons are shown in grey. The size of introns and exons in nucleotides is shown. Introns are not drawn to scale.
