What is epigenetics?

What makes monozygotic tweens different if they have almost the same genotype? If all cells in an organism have the same DNA sequence, why are there so many different cell types?

How complex is epigenetics?

Epigenetic changes on the DNA are diverse. Together they impact a wide range of biological processes such as organism development and disease progression.

Epigenetics and diet

Epigenetic changes on the DNA are affected by our diet, our physical activity, stresses and other environmental factors.

Epigenetics and diseases

Cancer cells carry epigenetic changes on their DNA, and metabolic diseases, such as diabetes, are highly affected by epigenetics.
