Two suppressor alleles map to prp-8. (A) Exon structure of unc-73 (32). The G → U substitution at the first base of intron 15 in the e936 allele, along with the cryptic SS activated by it, (−1, wt, +23) are indicated. (B) ³²P-RT-PCR products from independent RNA extractions were separated on 6% polyacrylamide denaturing gels. Bands corresponding to use of the different cryptic SS indicated. Quantification presented in Table 1.
