no, each pair is AT, TA, GC, or CG

That actually matters?
yes, it does.

yeah, you have two strands, buddy. one base on either strand.
Goodness, that's right!

So four to the three billion. My computer will be up all night calculating this one.

There are four, as hithere said... AT, TA, GC, CG. Makes a huge difference, between the pairs bond up like this, but it's one individual strand, that can have A, T, G, or C that makes up the DNA (The second strand just matches up the pairs). So it would just be 4^3000000000 that should give you the possible numbers. Then again, I wonder if that's exactly correct, because with a different combination, we wouldn't exactly be human any more, would we? I mean... from human to human, the majority of the strand is the same. Even in monkeys, we don't differ in terms of DNA by that much... most of the code is very similar. That being said, there really aren't tht many combinations, as there has to be some of it that can't really be changed, right?

I was just curious about the storage capacity of the human genome.
