Genetics determines what is transcribed, while epigenetics determines how much is transcribed. Remember that negatively charged DNA is wrapped around positively charged histone proteins like beads on a string in the nucleus. Epigenetics primarily changes how tightly the DNA is condensed. DNA that is
