In the January 25 Nature, Iyer et al. describe an elegant technique to identify transcriptional target genes throughout the genome (Nature 2001, 409:533-538). They combined chromatin immunoprecipitation (ChIP) with microarray analysis (DNA chips) to probe individual protein-genome interactions. The technique involved cross-linking, immunoprecipitation, PCR amplification and fluorescent labeling, followed by hybridization to microarrarys containing genomic DNA. They searched the yeast genome fo
