Welcome to r/science! This is a heavily moderated subreddit in order to keep the discussion on science. However, we recognize that many people want to discuss how they feel the research relates to their own personal lives, so to give people a space to do that, personal anecdotes are now allowed as responses to this comment. Any anecdotal comments elsewhere in the discussion will continue to be removed and our normal comment rules still apply to other comments.

Chromatin unravels at a particular gene involved with anxiety, leaving it susceptible to protein-gene interaction (change in dna) and priming the brain for continued alcohol use and dependence.

What about huge doses of alcohol every day?


HurpDurp54 OP t1_it0auyq wrote

Epigenetics is when the environment, or in this case, behavior and consumption of alcohol can change DNA expression. In itself, it does not affect gametes, it is simply a change in expression (it becomes available to transcription proteins). Part of the discussion describes how some people may be more suceptible to these DNA expression changes, and may explain hereditary addiction. Possibly it is a mechanism to keep the brain in homeostasis.

Phenotype = genotype (your genes) + environment (your life, diet, behavior, habits, etc)

Epigenetics is about the expression of your genes, i.e. chages that can occur without having a DNA change.
