The fact that two strands composing a DNA molecule are called antiparallel has to do with the orientation of the sugar-phosphate backbones. In the DNA double helix, one strand runs in the 5' to 3' direction, while the complementary strand runs in the opposite 3' to 5' direction. This antiparallel arrangement is crucial for the proper base pairing and structure of the DNA molecule.
