The moderately repetitive DNA sequences of Caenorhabditis elegans do not show short-period interspersion.

In these studies we show that the moderately repetitive DNA sequences of Caenorhabditis elegans are not arranged in the characteristic short-period interspersion pattern of most eukaryotes. Rather, the moderately repetitive sequences are arranged in long arrays as in Drosophila and Apis. These findings indicate that this type of arrangement is more phylogenetically diverse and hence less exceptional than previously believed.
