Fast Facts: 1  Alterations to chemicals attached to DNA, known as epigenetic changes, affect how genes do their work and have been linked to colon cancer. 2  A new study of six different cancer types found distinctive epigenetic changes in all of them.These insights into the cancer epigenome could provide a foundation for development of early screening or preventive treatment for cancer,â Timp says, suggesting that the distinctive methylation âfingerprintâ could potentially be used to tell early-stage cancers apart from other, harmless growths.
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.
