Is DNA binary?

Everybody learns in school that DNA is formed by bases A, T, G, C. However, A always bonds with T and G with C, so there are only two combinations possible. Does that mean that our genetic code is binary as computers 0s and 1s?

No, because even though A always binds with T, it matters which strand the A is on.  So, let's look at two DNA strands like this:

CTAGGC <-- One dna strand  
GATCCG <-- It's complement DNA strand

That would NOT be the same thing as:

CAAGGC  
GTTCCG

That's why DNA has four combinations possible per base and not two.
