Genetic makeup – Although individual genes may make you more susceptible to some diseases, your DNA is not an unchanging blueprint for your life. Emerging research shows that your genes may be influenced by everything in your environment, as well as your experiences, attitudes, and beliefs. That means it is possible to change the way genes are activated and expressed. Simply put, our gene’s do not define our biology.
Here is an enjoyable and informative Ted Talk given by Dr. Courtney Griffins explaining what epigenetics is and how our genes are influenced by certain enzymes that help turn genes on and off. These enzymes are specifically involved in relaxing DNA that is normally tightly coiled up in our cells. Dr. Griffin is now an Assistant Member in the Cardiovascular Biology Research Program at the Oklahoma Medical Research Foundation after receiving her B.A. from Harvard University and her Ph. D. from the University of California San Francisco School of Medicine
