If both the strands of $DNA$ are copied, two different $RNAs$ (complementary to each other) and hence two different polypeptides will produce; if a segment of $DNA$ produces two polypeptides the genetic

information machinery becomes complicated. The two complementary $RNA$ molecules (produce simultaneously) would form a double stranded $RNA$ rather than getting translated into polypeptides.
