What does it mean that DNA is antiparallel?

0:15

Antiparallel means the two strands of a DNA double helix run in opposite directions. One strand runs from the five-prime end to the three-prime end while the other runs from three-prime to five-prime. This orientation is essential for proper base pairing and for the enzymes that copy and read DNA.
