This is part 2 on what is epigenetics. All our stem cells have exactly the same DNA but as epigenetics “expresses” certain genes they become unique and very different cell types. Like muscle, heart, skin, etc. Each stem cell becomes one type of cell in our bodies. Once it is transformed it and all its descendants remain that cell type.

Nature is our DNA and what is hard programmed into us but Nurture is that part of epigenetics that is changeable by what we eat, how we think, what we believe and how much stress we have in our lives. I use the example of a computer a lot in my BLOGs but a piano is a great example as well. The keys are our DNA (hard-wired for a sound) but the pianist “plays” the piano by hitting (expressing a key and a sound) and the order that keys are played. This gives us the infinite different types of piano music we have.
