Guest guest Posted January 19, 2012 Report Share Posted January 19, 2012 Hi Lou I don't know much about this topic, but I'm wondering if you saw this interesting doco on ABC recently which touched on this in the context of twins studies? The second episode is still available to watch on iview. http://www.abc.net.au/iview/#/series/3396737 Cheers Kate > > Hi group, > > A few months ago I came across epigenetics and the four molecular building blocks of life (DNA, Lipids, Protein and Carbohydrate). Epigenetics is particularly fascinating to me. I got an elementary understanding from what I read but I'm hoping that you guys would chime in with your own understanding so I can get an idea of whether I'm on the right track. > > So...as I understand, epigenetics opens up a new dimension to the nature/nurture argument, with epigenetics changing the way we understand the environmental factors that impact changes in the functions of DNA. Apparently genes can be turned on and off (ummm, maybe turned down?) according to the epigenetics that attach to it and these epigenetics react to and are stimulated by environmental factors which, lead to changes in the behaviour of the gene. > > This information is full of hope for me, given a family history of mental illness, particularly when I consider my daughter. What do you guys know/think about epigenetics? Do you think I'm on the right track with my understanding? > > Lou > Quote Link to comment Share on other sites More sharing options...
