Repeated sequences cloned from the DNA of the sea urchin S. purpuratus were used as probes to measure the lengths of individual families of repeats. Some probes reassociated much more rapidly with preparations of long repeats than with short repeats while others reassociated more rapidly with short repeats than with long repeats. In this way two of five cloned repeats were shown to represent families with a great majority of sequences in the long class. One represented a family with similar number of long and short class members. Two were members of predominantly short class families - The cloned repeats representing long class families, formed more precise duplexes than those representing short class families. Thermal stability measurements using S. purpuratus or S. franciscanus driver DNA showed that precise repetitive sequences have as great an interspecies sequence difference as the less precise repeats. Thus the precision of many families may result from recent multiplication rather than from selective pressure on the DNA sequences. Measurements of evolutionary frequency change show a clear correlation between the frequency change and the size of families of repeats in S. purpuratus. Comparison with S. franciscanus indicates that many of the large size families in S. purpuratus are those that have grown in size since these two species diverged.
