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.
Answer Wiki. Antiparallel DNA strands occur naturally because the complementary base pairs would not be able to bond together via hydrogen bonds. It is important to maintain hydrogen bonds since these can easily be broken down by certain enzymes during replication and then quickly form again with the newly-formed complementary strand.
