The two strands are complementary, so the information needed to make either strand is automatically contained in the other strand.
Also, the two strands of a DNA double helix are held together only by weak hydrogen bonds. This makes it easier for an enzyme (DNA helicase) to unwind and separate the two strands from each other in order for another enzymes (DNA polymerase) to copy a portion of one strand from each exposed strand ... using the complementarity of bases mentioned above ... to make two new strands, each complemetary to the one it was copied from.

weak hydrogen bonding between base pairs allows DNA to unwind, the bases have complimentary bases so only one base fits in each base, strong bonds along backbone stop DNA breaking up along its length during copying
