WebHeterochromatin is first erased by removing the gene encoding a key chromatin modifier (for example, a KMT or HDAC). The re-introduction of that gene into otherwise wild-type cells allows heterochromatin re-establishment; however, cells lacking a heterochromatin establishment factor are unable to assemble heterochromatin 24 .
