Figure 2From: Evidence for 5S rDNA Horizontal Transfer in the toadfish Halobatrachus didactylus (Schneider, 1801) based on the analysis of three multigene familiesU2 snRNA gene organization in Halobatrachus didactylus. (a) Different regions of the U2 snRNA represented schematically. (b) 3’ end alignment of the U2 spacer; 3’b: 3’ Box; D: Putative DSE element; RE: Regulator Element; P: PSE element. (c) 5' end alignment of the U2 spacer; Hdi: Halobatrachus didactylus; Dla: Dicentrarchus labrax; Dpu: Dicentrarchus punctatus. (d) Alignment of the DSE element with those obtained from other species.Back to article page
