Interesting information about epigenetics:

Potential energy landscapes identify the information-theoretic nature of the epigenome

Garrett Jenkinson, Elisabet Pujadas, John Goutsias, Andrew P Feinberg

“Epigenetics is the study of biochemical modifications carrying information independent of DNA sequence, which are heritable through cell division. … By viewing methylation maintenance as a communications system, we introduce methylation channels and show that higher-order chromatin organization can be predicted from their informational properties. Our results provide a fundamental understanding of the information-theoretic nature of the epigenome that leads to a powerful approach for studying its role in disease and aging.”
