Document Summary
Scientists believe that this answer lies in the area between our genes (like dark matter in the universe) Same key genes that make other organisms (e. x. chimpanzees) make out organization! Example: mice - twins; both have a genes agouti - in yellow mouse, it is switched on all the time; mouse keeps on getting fatter/brain does not tell it that it is full! Methyl molecule is attached to the brown mouse, which shuts down area in brain that tells you when you are full (like hugging dna - hugging tightly = hidden from cell, shutting off gene expression) Differences in cells from different areas of the body, deals with switching on and off cell components; switches on cells are very stable. Seen in almost half patients receiving these drugs. Environment molds our epigenome; new studies are even showing that more than just our genes are passed along to our children.
