Mapping Chromatin in the Fruit Fly

In a study published last week in PLoS Genetics, scientists at Columbia and NKI used a combination of ChIP-chip data and bioinformatic analysis to assemble a genome-wide map of chromatin organization in the Drosophila genome. Looking at 29 broadly selected Drosophila chromatin components, they found that at least 50 percent of all fly genes are organized into chromatin domains, and that these genes have similar functions and are often expressed together during development.
