Problem: Since the two strands of the DNA molecule are complementary, for any given gene:A. The RNA polymerase can bind to either strand.B. Only one strand actually carries the genetic code for a particular gene.C. Each gene possesses an exact replica that can be used should a mutation occur.D. A gene transcribed in the 5' to 3' direction on one strand can be transcribed in the 3' to 5' direction on the other strand.

The complementary nature of the double-stranded DNA shows that it follows specific base-pairing principles: A pairs with T, and G pairs with C. This would have particular effects on gene expression. The immediate effect of this complementarity is that the partner strands can never be identical with one another.
