Organization of DNA sequences near the centromere of the Drosophila melanogaster Y chromosome

Abstract

The structural analysis of a yeast artificial chromosome clone from Drosophila melanogaster enriched in dodecasatellite sequences has led us to find a new retrotransposon that we have called Circe. Moreover, this retrotransposon has allowed the isolation of a contig encompassing approximately 200 kb near the centromere of the Y chromosome, providing an entry point into a region from which very little sequence information has been obtained to date. The molecular characterization of the contig has shown the presence of HeT-A telomeric retrotransposons close to the centromere of the Y chromosome, suggesting a telocentric origin for this submetacentric chromosome.
