Answer:
It would be
G C T A T G C A T C G C A
C G A T A C G T A G C G T
Explanation:
You might want to double check if you put it in right but this is what I got. The bases that pair up with each other are A & T and G & C. You look at one strand and then you look at the other strand and find the right one to go with it. If in the first letter of the first strand was G then the base pair would be C and etc.
