Antiparallel vectors. In a Euclidean space, two directed line segments, often called vectors in applied mathematics, are antiparallel, if they are supported by parallel lines and have opposite directions. In that case, one of the associated Euclidean vectors is the product of the other by a negative number.
The two DNA strands are complementary and parallel, but they go in opposite directions. The antiparallel structure of DNA is important in DNA replication because it replicates the leading strand one way and the lagging strand the other way. The antiparallel strands allow for the formation of hydrogen bonds between the nitrogenous bases of DNA. If the strands were not antiparallel these nonsymetrical hydrogen bonding interactions would not be possible. It is important that CG interactions have three H- bonds, and AT have two H-bonds.
