The strands that make up DNA are antiparallel. This means that
A) one strand is positively charged, and the other is negatively charged.
B) the base pairings create unequal spacing between the two DNA strands.
C) the 5´-to-3´ direction of one strand is counter to the 5´-to-3´ direction of the other strand.
D) the twisting of the DNA molecule has shifted the two strands.
E) purines bond with purines and pyrimidines bond with pyrimidines.

Antiparallel means that the 5´-to-3´ direction of one strand is oriented opposite to the 5´-to-3´ direction of the other strand. This creates the characteristic double helix structure of DNA.
