But a burgeoning field known as epigenetics is showing that many cancers may not be caused by mutations in genes, but by chemical modifications that alter how the genes function. Such modifications to genes are epigenetic-literally on top of or related to changes in the DNA sequence.
Epigenetics literally means above or on top of genetics. It refers to external modifications to DNA that turn genes on or off.. These modifications do not change the DNA sequence, but instead, they affect how cells read genes. Examples of epigenetics.Epigenetic changes alter the physical structure of DNA.One example of an epigenetic change is DNA methylation â the addition of a methyl group, or a chemical cap, to part of the DNA molecule, which prevents certain genes from being expressed. Another example is histone modification.Histones are proteins that DNA wraps around.ne example of an epigenetic change is DNA methylation â the addition of a methyl group, or a chemical cap, to part of the DNA molecule, which prevents certain genes from being expressed.
