Figure 1.

The genomic organizations of the inx2 and inx3 genes. inx2 and inx3 map to chromosome positions 6E4–5 on the X chromosome and 98E4–6 on chromosome 3, respectively. EcoRI, BamHI, and SalI restriction sites are shown, and the direction of transcription is given by the arrows. Genomic DNA is indicated by horizontal lines, coding regions by filled boxes, noncoding sequences by open boxes, and intronic regions by a “v.”
