DNA is just a small part of what makes up the functioning whole of an organism. The Transcriptome, Proteome, and the Metabolome are just as important to determining the outcomes of genes. It's like understanding what parts are in your car but not knowing how much gas is in the tank, how far the pedal is pressed, or even what gear you're in. It's still an incomplete picture. Disclosure: I studied cancer metabolism in grad school so I'm a little biased to think that the Metabolome is the functional endpoint of genetics and all its associated modifiers.
