Localization of a vertebrate telomeric sequence in the chromosomes of two marine worms (phylum Annelida: class polychaeta).
Using the fluorescence in situ hybridization (FISH) technique, the presence of the vertebrate telomeric sequence (TTAGGG)n was found in the chromosomes of two marine polychaetes belonging to two separate orders: one errant, Platynereis dumerilii (family Nereidae), and the other sessile, Pomatoceros lamarckii (family Serpulidae). This sequence was exclusively present at the ends of the chromosomes in both species.
