All DNA of course has highly specified code in the sequence of arrangements of its bases.
Um, exactly how specified do you think it is? Given that, for most proteins you can alter as much as 80 or 90% of them without changing their function or catalytic activity, isn't DNA actually
not all that specific, much as we might expect for something that evolved by mutation and random selection?
It utilizes this as the very blue prints for each cell in the construction of the entire living organism.
Uh, no, in fact your DNA contains absolutely no blueprints at all. With very few exceptions there's no homology between DNA and anatomy, either on a cellular or organismal level. DNA isn't anything like a "blueprint."
