The function of DNA goes well beyond the physical.

It not only stores genetic information, but also other information on other levels.

Just imagine how much information on every level imaginable could be stored within you right this second... considering the following:

With this small amount of DNA, a computer would be able to hold 10 terabytes of data, and perform 10 trillion calculations at a time. By adding more DNA, more calculations could be performed. Unlike conventional computers, DNA computers perform calculations parallel to other calculations.
