Representative dot-blots from the screening of cDNA clone and consensus sequences of three germline-specific repetitive DNA families. (a) Two identical membranes were dot-blotted with four cDNA clones and hybridized with probes prepared from Rsa I-digested testis cDNA (top) and Rsa I-digested somatic cDNA (bottom). The differentially expressed clones are indicated by arrowheads. (b) Membranes were blotted with somatic (S) and germline (G) genomic DNA and hybridized with probes prepared from each clone. The testis genome-specific signal is indicated by an arrowhead. (c) Each consensus nucleotide sequence was deduced from the inserts of germline genomic DNA clones. Upper arrows: the direct repeats. Lower arrows: the inverted repeats. The other notations correspond to those in Fig. 1. The sequence data obtained here have been deposited in GenBank (LC667642–LC667644).
