Abstract
We have isolated two yeast artificial chromosome (YAC) clones from Drosophi la melanogaster that contain a small amount of dodeca satellite (a satellit e DNA located in the centromeric region of chromosome 3) and sequences homo logous to the telomeric retrotransposon HeT-A. Using these YACs as probes f or fluorescence in situ hybridization to mitotic chromosomes, we have local ized these HeT-A elements to the centric heterochromatin of chromosome 3, a t region h55. The possible origin of these telomeric elements in a centrome ric position is discussed.
