Gene Switch

Why do identical twins lead different lives due to different lifestyles? Why do some people still have trouble escaping the fate of "relapse" even if they are determined to quit drugs? Do patients with bulimia and drug dependence really suffer from personal will? The answer is epigenetics, the idea that genes change in response to changes in people's lifestyles, turning their functions on or off. From the basic definition of epigenetics, its impact on humans, and the difference between epigenetics (shorter time) and genetic variation (longer time), this book explains that epigenetics is the study of reversible and heritable changes in gene function without changes in the DNA sequence. In addition, the book also cites a large number of examples: the way a mother raises her children will have a great impact on the child's brain, and children who grow up in an environment full of maternal love are more likely to live longer; citing the "Dutch Winter Hunger Incident" proves that if the mother cannot take in enough nutrients during pregnancy, babies born in a nutritionally deficient environment will be more susceptible to lifestyle-related diseases as adults. Through a large number of scientific experiments and the latest research results, the author emphasizes the importance of epigenetics to humans, clarifies that turning genes on or off is real, and encourages everyone to rethink their lifestyles and the way we communicate with others.
