: The core narrative focuses on how chemical "tags" act like switches, turning genes on or off without changing the underlying DNA sequence.
The guide follows a historical and conceptual path to explain why we aren't just "puppets" of our DNA:
: It begins by pulling apart the double helix to establish the basics of genetics and cell biology. Introducing Epigenetics: A Graphic Guide
: How the "spools" DNA wraps around affect gene expression.
: The chemical processes that silence or activate genes. : The core narrative focuses on how chemical
: The final chapters explore how understanding these "messengers" allows for massive leaps in medicine and disease treatment. Key Concepts Covered
In , author Cath Ennis and illustrator Oliver Pugh translate one of the most complex frontiers of modern biology into a visually driven narrative. The book serves as a "non-fiction comic" that bridges the gap between fixed genetic code and the dynamic way our bodies actually function. The Storyline of the Guide : The chemical processes that silence or activate genes
: Explaining why two people with the same DNA can develop different diseases or traits based on their environment.
