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.

Best Answer: The two strands are antiparallel because of the complementarity of the nucleobases that comprise them: DNA is comprised of four nucleobases or bases: cytosine, guanine, adenine, and thymine. The thing is, they pair up with each other in only one way: C-G and A-T, and vice verse.
