Abstract
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.
摘要
利用荧光原位杂交（FISH）技术，在分属于两个不同目的两种海洋多毛纲动物的染色体中发现了脊椎动物端粒序列（TTAGGG）n：一种是游走性的杜氏阔沙蚕（沙蚕科），另一种是固着性的拉氏缨鳃虫（缨鳃虫科）。在这两个物种中，该序列仅存在于染色体末端。
