Figure 2.
A schematic representation of V-SINEs. Each V-SINE has a composite structure, namely, a tRNA-related region and a tRNA-unrelated region. The latter can be further divided into the central conserved domain, a (TG)n tract and a 3′ tail that is characteristic of each V-SINE family but differs considerably among families. Short bars with half-arrowheads indicate positions and directions of oligonucleotide primers used for PCR.
