Southern blot analysis of DNA in wild-type (Oregon-R) and Su(UR)ES strains. DNA from adult heads and larval salivary glands (SG) was extracted as described in Materials and Methods and hydrolized by HindIII. The same blot was hybridized with probes containing 359-bp satellite (a), histone gene (b), and DNA of 28S rRNA gene (c). Two probes from the 3′Ubx and 5′Ubx exons were hybridized to other blot. DNA of the rosy gene was used as a standard (d).
