Newly evolved highly repeated DNA sequences of Tupaia glis (Tupaiidae, Scandentia).

We have studied highly repeated DNA sequences of Tupaia glis (Tupaiidae, Scandentia) with restriction endonucleases and Southern blotting techniques. Five highly repeated DNA fragments have been isolated from T. glis and hybridized with genomic DNAs (cleaved by different restriction enzymes) of several non-human primate species and one insectivore (E. europaeus), in order to highlight eventual differences or similarities of their highly repeated DNA sequences. Our first preliminary findings suggest that the newly isolated highly repeated DNA fragments of T. glis are distinct from both non-human primates and insectivore, the two taxonomic groups considered most similar to the Tupaiidae.
