Epigenetics- You are what you eat,breathe, feel, etc...

"Our understanding of genetics is currently undergoing a paradigm shift," says Melanie Ehrlich, a molecular biologist at the Tulane Cancer Center. "It is now commonly acknowledged among scientists that it is not enough to look to DNA as the sole determinant of heredity."

Ehrlich is referring to a complicated chemical switchboard known as the epigenome that switches genes on and off. Scientists are learning that looking at DNA alone is not enough to determine heredity as they are now learning that epigenome is highly reactive to its environment.
As more light is shed on epigenetics, scientist are confident that cures for diseases and even an antidote for aging can be found. Read more here.
