Epigenetic Modifications(表观遗传修饰)All Epigenetic Modifications Antibodies

Epigenetic changes can modify the activation of certain genes, but not the sequence of DNA. Additionally, the chromatin proteins associated with DNA may be activated or silenced. This is why the differentiated cells in a multi-cellular organism express only the genes that are necessary for their own activity. Histone modifications are epigenetic marks that effect gene expression patterns.
