The two strands of DNA are complementary. That is, there are four bases and each base in one strand interacts with only one base in the other strand. If you know all the bases in one strand you will be able to figure out all the bases in the other strand. If you are given a strand with the sequence ATTCAG, you know the strand it interacts with has to be TAAGTC. For example, A interacts only with T and C interacts only with G.
