Epigenetic changes are based on biochemical modifications that can activate, reduce, or disable the activity of some genes by: a) the addition of a methyl group to a cytosine residue, followed by a guanine sequence in a CpG dinucleotide (methylation is often associated with reduced gene activity); b) changes in the chromatine structure through chemical modifications, especially acetylation or methylation of histone proteins, which recruit other proteins such as transcription factors and repressors that together determine the activity state of specific genes or sets of genes; and c) changes in the genetic messages transcribed.
