SUPPLEMENTL FIGURE 1 C Supplemental Figure 1. pproach for removal of snorns from Rpl13a gene. () Wild type Rpl13a exonintron structure is shown, with exo in black and intronic snorns in red rectangles. Numbering in black reflects the limits of the exonic sequences, relative to the tralation start of the gene. () Enlarged detail of snorncontaining intro is displayed. Numbering in red reflects the limits of the intronic sequences and the snorns, relative to the tralation start of the gene. (C) Targeting cotruct was generated by removing nucleotides 1831363 encoding U3a, nucleotides 181188 encoding U33, nucleotides 78143 encoding U34, and nucleotides 311399 encoding U3a.
