Explanation:

<h3>The antiparallel arrangement of the two strands is what causes the twist. Because the strands run in opposite directions, they pull the sides of the molecule in opposite directions, causing the whole thing to twist around itself. Most naturally occurring DNA spirals clockwise.</h3>
