Some example of the chemical marker that is associated with DNA is epigenetic factors and histone proteins.
Epigenetic factors are compounds that regulate genetic expression. It works by causing changes in the gene, altering the way your body interprets a DNA sequence. These changes are temporary; they don't cause mutation nor they are heritable. Some forms of changes that are caused by epigenetic factors are methylation and DNA remodeling.
Histone proteins are proteins in eukaryotic cells that have dual functions: keeping the DNA in a compact form and regulating the tightening and loosening of DNA strands that regulate gene expression.
