«Epigenetics» is an educational science documentary, especially addressed to young people. This is the first Italian documentary about a growing sector of the scientific research. Epigenetics investigates how environmental experience chemically influences gene expression, without changes in the DNA sequence. In other words, epigenetics investigates how DNA behaves and responds to the environment, allowing every living being to rapidly adapt to external influences. The "game" metaphor links the entire documentary. Thank to Lego, flipper, billiard, origami, and other games, the documentary tries to explain a complex matter and the creativity that lies at the bottom of scientific research.
