We know that different protein complexes can interact with specific proteins (histones), in which DNA is wound, and thus to determine active or inactive genes. Making protein complexes bind to histones and to regulate the activity of genes can small chemical groups, - says Hansen.
Scientists have studied in detail the complex PRC2. This complex can attach a small chemical group - methyl - to the histones. When the marker is present, with the histones can bind protective systems, which turns off the gene.
