The two chains of DNA helix have anti-parallel polarity. It means, if one chain has the polarity 5'→3', the other has 3'→5'. This means if one end of the double helix has a phosphate group (5' end) on one strand, it will have a hydroxyl group (3' end) on the other strand. The strands are complementary, meaning the sequence of one dictates the sequence of the other through specific base pairing.
