Analysis of the seven loci at which a SINE or a LINE was inserted during the evolution of Cetartiodactyla. (A-G) Data for the loci M11, KM14, HIP4, HIP24, AF, HIP5, and INO. Shown are (a) products of PCR and (b) and (c) the results of hybridization experiments using the SINE (or LINE) unit and the flanking sequence as probes, respectively. The results of hybridization with different retroposon probes are shown in d-f. The probes used were: Ed, MER; Fd, Bov-A; Fe, CHR-2; Gd, ARE; Ge, Bov-B LINE; and Gf, LINE1.
