title: Sequence organization in the DNA of three Selachians.
abstract: The DNA interspersion pattern in 3 Selachians (R. asterias, T. marmorata and S. stellaris) has been studied through the reassociation kinetics of short (0.3 Kb) and long (2.5 Kb) DNA fragments. Preliminary results show that most of the DNA (approximately 80%) of these organisms is arranged according to a short-period interspersion pattern. A notable resemblance to the pattern previously described in the teleostean Salmo trutta has been observed.
