New Computers?

[8Shade8]

What if you could have a computer that had hundreds of useless Terabytes of memory? There is a way, and a freind of mine has an idea she is trying to get a patent on.

Take a DNA strand. People are still trying to figure out what everything on it does, what parts of it do what and what parts of it control different body aspects.
It takes a computer years to just analyze a single strand of DNA. There are four chemicals and each one have a correspondant that is on the other side of the strand. Well, excuse me for my science illiteracy, but here is the idea:

She was thinking that if you could "reformat" a strand of DNA, erase all of the chemicals but two like this:

A>B
C>D
(there is always these four chemicals on a strand of DNA and I dont feel like looking for them online; I will denote them as A,B,C and D)

She will "reformat" it like this:

A>B
A>B
A>B
A>B

If a computer was programmed to read A as 1 and B as 0 (thus we have binary) we could make computers out of DNA. All she has to do is get someone to make a computer compact enough to change the chemicals and "reformat" and "write" the code. The problem is, is that the computers that the scientists have, that do this for experiments are HUGE.

I think it would be cool if she could pull this off, and become really rich, and just think, in 30 years if they miniturize the tools needed to do that, we could never have to upgrade any thing. Your entire computer could run off of one strand of DNA.

It seems unthinkable now, but they said the same thing about flying and other things a hundred years ago.
