They face in the opposite direction and you could predict the properties of one from base pairing rules of the other but they're not the same.

它们是反向的,尽管你能够通过一条链上的碱基序列,预测另一条链的序列,但这两条链是不同的

Well you do that by this Watson-Crick base pairing, so I know if I have I know what messenger RNA to make from that because I have to satisfy these base pairing rules.

依据的是沃森克里克碱基互补配对原则,如果给我一个ACGCGA的序列,就能知道转录出的mRNA会是什么,因为我必须满足碱基配对原则
