Fascinating Genetics Research - Epigenetics

An article in Discover Magazine titled DNA Is Not Destiny explores the fascinating new field of epigenetics research.

In a nutshell, researchers are discovering that although DNA provides a roadmap for each human being, something needs to tell the genes what to do. An extra dose of vitamin, exposure to a toxin, or loving parenting not only affects the next generation, but the following generations as well.

"Put simply, and as bizarre as it may sound," the article says, "what you eat or smoke today could affect the health and behavior of your great-grandchildren."

Randy Jirtle, a professor of radiation oncology at Duke University and epigenetics researcher, says, "Epigenetics is proving we have some responsibility for the integrity of our genome. Before, genes predetermined outcomes. Now everything we do—everything we eat or smoke—can affect our gene expression and that of future generations. Epigenetics introduces the concept of free will into our idea of genetics."
