    Epigenetic discovery suggests DNA modifications more diverse than previously thought

    http://medicalxpress.com/news/2015-1...s-diverse.html

    The world of epigenetics—where molecular 'switches' attached to DNA turn genes on and off—has just got bigger with the discovery by a team of scientists from the University of Cambridge of a new type of epigenetic modification.

    Published today in the journal Nature Structural and Molecular Biology, the discovery suggests that many more DNA modifications than previously thought may exist in human, mouse and other vertebrates.

    Epigenetics (epi—the Greek prefix meaning 'on top of') is the study of how genes are switched on or off. It is thought to be one explanation for how our environment and behaviour, such as our diet or smoking habit, can affect our DNA and how these changes may even be passed down to our children and grandchildren.
