TED-ED: What is epigenetics? - Carlos Guerrero-Bosagna

The video explores why identical twins can differ despite having the same DNA, focusing on epigenetics, which studies how DNA interacts with molecules to activate or deactivate genes. Epigenetic changes, influenced by environmental factors, can affect gene expression and lead to different traits and health outcomes. These changes can persist through cell divisions and even across generations. However, they are not always permanent and can be influenced by lifestyle. The video highlights the potential of understanding and manipulating the epigenome to improve health and treat diseases.
