Ok, so how does DNA build things? Say, even something as simple as a virus. The virus inserts its DNA or RNA or whatever, and it's coded into proteins. So how does the protein make a shape? Like in that T4 virus that looks like the lunar lander thing, how do the proteins assemble into the shape of the head? That complex, round shape? Or to make the legs, etc. I guess what I'm asking is how do proteins end up forming shapes?
