Osmosis video - Epigenetics

Epigenetics is the study of how environmental and lifestyle factors can change the way our genes are expressed without actually changing the DNA sequence. These epigenetic changes can be passed down from one generation to the next, which means that they can influence our health even if we don't have any direct descendants.

There are a number of different epigenetic mechanisms, but some of the most common ones include DNA methylation, histone modification, and microRNA expression. Each of these mechanisms can either promote or suppress gene expression, and they can be affected by things like diet, stress, exposure to toxins, and social interactions.
