Mapping of mononucleosomal DNA in wild type Drosophila


ABSTRACT: Crosslinked chromatin from wild-type flies was digested with micrococcal nuclease. Mononucleosomal DNA was gel-purified and hybridized to Affymetrix tiling arrays.

ORGANISM(S): Drosophila melanogaster

Comparative genomics of nucleosome positions provides a powerful means for understanding how the organization of chromatin and the transcription machinery co-evolve. Here we produce a high-resolution reference map of H2A.Z and bulk nucleosome locations across the genome of the fly Drosophila melanogaster and compare it to that from the yeast Saccharomyces cerevisiae. Like Saccharomyces, Drosophila nucleosomes are organized around active transcription start sites in a canonical -1, nucleosome-fre  ...[more]
