(D) $DNA$ is a type of nucleic acid that forms the genetic material in many organisms.It consists of a long polymer of nucleotides.It is a double helical molecule.The two strands of $DNA$ run in opposite directions to one another,held together by hydrogen bonds.One strand of $DNA$ has a $5' \rightarrow 3'$ direction,and the other strand has a $3' \rightarrow 5'$ direction.This is why they are called antiparallel.This orientation is determined by the presence of a free phosphate group at the $5'$ end and a free $OH$ group at the $3'$ end of the sugar-phosphate backbone.
