"DNA is commonly referred to in textbooks of molecular biology as the "blueprint" for an organism. I think it is better not to call it a blueprint. I would rather call it a recipe or it is a bit like a computer program.

The difference between a blueprint and a recipe is that a blueprint is reversable, and a recipe is not. If you have a house and you have lost the blueprint you can reconstruct the blueprint by taking measurements, but if you have got a well prepared dish in a great restaurant you may enjoy the dish and you may dissect it and look at it in every detail but you cannot reconstruct the recipe."

Richard Dawkins
