| Abstract: | Summary The DNA interspersion pattern in 3 Selachians (R. asterias, T. marmorata andS. 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 teleosteanSalmo trutta has been observed. |
