Epigenetics is a relatively common term nowadays, but what does it actually mean? To put it simply, it refers to the study of changes in gene expression without any alteration in the underlying genetic code. It’s like a new chapter in our understanding of how genes and cells work together to regulate growth and development.
The epigenome, which is a dynamic layer of chemical markers on top of our genetic material, provides essential information about how our genes are used and can change throughout our lifetime. It is responsible for controlling which genes are turned on or off, determining how proteins are made, and influencing the overall function of our cells.
So why is epigenetics so important? Well, it is revolutionizing our understanding of genetics by showing us that our genes are not always our destiny. While genetic variations play a crucial role in our health and susceptibility to diseases, epigenetic changes can modify the way our genes are expressed, potentially leading to disease or, on the flip side, providing opportunities for prevention and treatment.
Epigenetics opens up a whole new world of possibilities, allowing researchers to explore topics such as how environmental factors can influence gene expression, how epigenetic changes occur during development and aging, and even how epigenetic modifications can be inherited from one generation to the next. By unraveling the mysteries of the epigenome, we can hope to gain a deeper understanding of human biology and potentially develop new therapies and interventions.

In the previous chapters, we learned about epigenetics and how it provides a deeper understanding of how genes work. In particular, we explored how the epigenome, which consists of chemical tags on our DNA, can determine which genes are active or inactive.
To learn more about the epigenome and its role in regulating gene expression, here are some common topics you can explore:
Americans see their primary care doctors less often than they did a decade ago. Adults under 65 made nearly 25% fewer visits to primary care providers in 2016 than they did in 2018, according to National Public Radio. In the same time period, the number of adults who went at least a year without visiting a primary care provider increased from 38% to 46%.
