Genes can either be on or off all of the time. Or be turned on only under special situations. How a gene is controlled is determined by these TFs. Some genes, … 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.
