It is believed that at the time of our birth—eye color,height,disease risk and even some aspects of our behavior are hardwired into our DNA. The crucial role of genetics in shaping our life cannot be denied but modern biology has revealed a far more dynamic picture. The fascinating field of epigenetics which shows how our genes are not fixed instructions but flexible scripts that respond to our environment, lifestyle and experiences. The understanding of scientists about human development,disease, health and inheritance is greatly influenced by epigenetics. This field has explained why identical twins become different over a period of time,how stress can leave biological scars and how diet and environment can influence not only our lives but also those of future generations.  Sup WHAT IS EPIGENETICS ? ...
