1) The twisting nature of DNA creates nonparallel strands.
2) One strand is positively charged and the other is negatively charged.
3) The 5' to 3' direction of one strand runs counter to the 5' to 3' direction of the other strand.
4) One strand contains only purines and the other contains only pyrimidines.
5) Base pairings create unequal spacing between the two DNA strands.
