It is NOTHING like a blueprint. That is one of the worse metaphors for DNA you could think of.
Really? If you design a car or a house, you need blueprints or architectual drawings. If you design an organism, what do you need? In DNA you do not only have the blueprint, but you have the mechanism to proceed and build it. Yes, you're right, DNA is much more than a blueprint. It incorporates the blueprint and proceeds to manufacture what it necessary for the organism to survive and replicate. It's the blueprint with the factory, tools and workers, all in one. It's a f@$#ing miracle!
