title: Repetitive DNA sequences located in the terminal portion of the Caenorhabditis elegans chromosomes.
abstract: We describe the distribution along the chromosomes of Caenorhabditis elegans of two repetitive DNA families, RcS5 and Cerep3 and interstitial telomeric sequences. Both families show, among other interesting features, a preferential location in the terminal 30% of the chromosomes. It is known that in these regions of the genome the frequency of recombination is much higher than in the central portion, genes are rarer and sequences important for chromosome disjunction may lie.
