HeT-A telomere-specific retrotransposons in the centric heterochromatin of Drosophila melanogaster chromosome 3.

A Losada1, M Agudo, J P Abad, A Villasante.   

Abstract

We have isolated two yeast artificial chromosome (YAC) clones from Drosophila melanogaster that contain a small amount of dodeca satellite (a satellite DNA located in the centromeric region of chromosome 3) and sequences homologous to the telomeric retro-transposon HeT-A. Using these YACs as probes for fluorescence in situ hybridization to mitotic chromosomes, we have localized these HeT-A elements to the centric heterochromatin of chromosome 3, at region h55. The possible origin of these telomeric elements in a centromeric position is discussed.
