Each pair is either AT or GC.   So 2^3000000000 will give me the number of possible combinations, right?

Replies The Samsoniteman Posted at 5:30 am on June 27, 2008 Only a tiny proportion of that actually functions in phenotype generation, however. shadowpool Posted at 11:11 am on June 26, 2008 Yup! My comp is still calculating btw.  :) Spasty Posted at 10:43 am on June 26, 2008 But isn't much of that identical in all humans? shadowpool Posted at 11:59 pm on June 25, 2008 I'm going to try 4^187500000 Then I'll raise that to the 16th.  Maybe it'll be less memory intensive.

My computer will be up all night calculating this one.   Use a recursive function.  It'll work perfectly! I'm attempting to use qalc which is an arbitrary precision calculator. Hopefully 2gb of ram is enough. h a t t Posted at 11:33 pm on June 25, 2008 Quote: from shadowpool at 11:27 pm on June 25, 2008 So four to the three billion.

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?
