Epigenetic mechanisms which involve biochemical alterations to DNA structure have been documented to result in heritable changes in gene expression. Unlike mutations, however, epigenetic changes do not involve changes in the primary DNA sequence, such that a nucleotide would change into a different nucleotide. Nevertheless, the field of epigenetics has been a fertile ground for […]
