WebSimple explanation of how genes turn on and off during cellular differentiation. WebGenes are "on" during demethylation and "off" during methylation. Histone modifications are another example of an epigenetic change. Depending on how close the histones are packed, it determines whether the gene is "off" or "on". Tightly packed histones prevent proteins from binding to the DNA, so it keeps the gene inactivated.
