摘要：

The repeated sequence TTAGGG is present at all tested vertebrate telomeres including those of humans and at the telomeres of evolutionarily very distant organisms such as trypanosomes and slime moulds. We tested for the presence of this sequence in the genome of the crustacean isopod Asellus aquaticus. Fluorescence in situ hybridization and BAL31 nuclease digestion demonstrate that the (TTAGGG)(n) sequence occurs at the extreme termini of the chromosomes and also at an interstitial site.
