Cloning and physical mapping of Atlantic salmon (Salmo salar L.) telomeric sequences

Article Abstract:

The hypothesis that telomeric sequences are almost totally lost during Atlantic salmon (Salmo salar L.) chromosome fusion events seems to be supported by data. DNA containing telomeric sequences from the salmon has been cloned and sequenced. A cloned probe binds only at extreme termini, and not at interstitial sites, in both low- and high-stringency conditions
