Answer
DNA and RNA strands are referred to as directional because they have a 3' end and a 5' end. Distinct directionality exists in these strands because the 3' end has a carboxyl group and the 5' end has a phosphate group. These functional groups are therefore responsible for differentiating the two ends of the nuclei acid strand.
