DNA has two strands. If the sequence of nucleotides of one strand was known, is it possible to use that information to determine the sequence of the second strand

Question

blues · Answer

The two strands of DNA are complementary. That is, there are four bases and each base in one strands interacts with only one base in the other strand. So if you know all the bases in one strand, will you be able to figure out all the bases in the other strand?

blues · Answer

For example, A interacts only with T and C interacts only with G.

So if you are given a strand with the sequence ATTCAG, you know the strand it interacts with has to be TAAGTC. Does that make the question clear?
