What is meant by the description "antiparallel" regarding the strands that make up DNA? One strand is positively charged and the other is negatively charged. One strand contains only purines and the other contains only pyrimidines. The 5' to 3' direction of one strand runs counter to the 5' to 3' direction of the other strand. The twisting nature of DNA creates nonparallel strands. Base pairings create unequal spacing between the two DNA strands.
