In recent years, our view of how gene expression is controlled has changed dramatically. The discovery of enzymes that modify histones has revealed that transcription is an enzymically driven process. Such modifications can recruit specific proteins and mediate chromatin changes that affect transcription either positively or negatively. Important biological pathways leading to cell proliferatio...
