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.
