Genomic biology: The epigenomic era opens

Stephen B. Baylin1 & Kornel E. Schuebel1

Readout of information from the genome depends on intricate regulation of how DNA is packaged by proteins. The great endeavour to reveal how this packaging operates pan-genomically is now under way.

A new era is opening for biologists involved in understanding cellular systems. It is exemplified by papers by Mikkelsen et al.page 553 of this issue)1 and Barski et al.Cell)2 — they describe the kind of unprecedented insights that are emerging from investigations of how a single mammalian genome can be regulated to produce different cell types.
