Figure 3.
The widespread distribution of V-SINEs among vertebrates. Analysis by PCR was performed using the DNA from 77 vertebrate species as template and two oligonucleotides specific for the tRNA-related region and the central conserved domain of V-SINEs as primers. The Lun1, Ras1, Ac1, and Lam1 SINE families were characterized for the first time in this study. A plus sign indicates a species in which the presence of V-SINEs was strongly suggested by our analysis. A question mark indicates the absence of strong evidence for V-SINEs. Partner LINEs with the same 3′ tails as V-SINEs are depicted on the right.
