The science of epigenetics looks at those molecular mechanisms, those intricate ways in which our DNA is literally shaped, genes turned on and off based on the exposures to the environment, to where we live and to where we work.
La ciencia de la epigenética observa  esos mecanismos moleculares, esas formas intrincadas en que  nuestro ADN es literalmente ajustado genes que se encienden y se apagan con base a lo que se exponen  en el ambiente en donde vivimos y trabajamos.
