Epigenetics – Changes to genes by the
environment How does this happen?
Genes code for proteins
* Proteins → structures
And, indirectly, of traits But many also regulate other genes
The environment effects all of these
The science of epigenetics -changes in the genome that are brought about through experience and are passed on to the next generation
-sequence of amino aids is the same, but whether the genes are turned on or not changes 18 5/22/13 DNA

Each made up of long strands of DNA
The long strands are tightly wrapped
Like the rubber bands in a golf ball
But wrapped around histone...
