DNA is not uniqely describable by a sequence of nucleic acids? And where does the information come from that determines how its genes operate?

The genetic code is a program. But instead of binary and bytes it uses a base four system of four nucliotides divided into tri-nucliotide codons of giving a total of 64 different codons. This program can't produce anything unless it is placed in an automated factory called a cell. One is useless without the other. Genes switch on and off and give instructions according to the chemical environment they are in, that is, the chemical environment inside the cell. At one point you were a single cell in a chemical solution that triggered the divide rapidly part of your program and you became a blastolyst and eventually an embryo. If a cell can be tricked into thinking it is in that environment again it can be used to make a clone under the right circumstances, but we currently can't do this sort of cloning with mammals but we can transfer DNA from a body cell into an egg cell and produce a clone that way.
NOTE: I refer to a cell as an automated factory as an anology. To believe that a cell really is an automated factory made by someone is as silly as an adult believing that Santa Claus is the one who puts the presents under the tree. Also, DNA is not a blueprint, it is more of a recipe. For example your DNA doesn't contain a map of your fingerprints any more than a blueberry muffin recipe contains a map of where to place the blueberries. Their location is the result of chance.
