The DNA Files - Rewriting Heredity: Environment and the Genome The Science Show presents another program in the series, The DNA Files. This week, Rewriting Heredity: Environment and the Genome. Our genomes are constantly at work, directing such vital functions as eating and breathing. Researchers are starting to understand that everything from diet to air pollution to stress has great influence on how our genomes function and what that might mean for our health. Beginning before birth, the environment around us triggers chemical changes to our DNA that influence health issues as complex as obesity and asthma.
