The members of each base pair can fit together within the double helix only if the two strands of the helix are antiparallelthat is, only if the polarity of one strand is oriented opposite to that of the other strand ....The antiparallel structure of DNA is important in DNA replication because it unzips the leading strand one way and the lagging strand the other way.

dna is antiparallel so that it will be able to maintain its twisted structure, so that it can fit its huge volume into such a small cell, and also the structure of the purines and pyrimidines combining is up and down which makes the dna more easy to maintain its antiparallel structure then a parallel structure

Well, if they were parallel individual nucleotides could not form proper bonds with their pairs.
