Smoking can result in changes in chromatin structure. For example, at certain parts of the AHRR gene, smokers tend to have less DNA methylation than non-smokers. After quitting smoking, former smokers can begin to have increased DNA methylation at this gene (the DNA becomes loosely-packaged euchromatin). What type of regulation is this?
A. Transcriptional
B. Post-transcriptional
C. Translational
D. Post-translational
E. Epigenetic
E. Epigenetic
