| I: | DNA – deoxyribonucleic acid – is the genetic material, at least for the majority of organisms. |
| II: | RNA though it also acts as a genetic material in some viruses, mostly functions as a messenger. |
| III. | RNA can function as an adapter, structural, and in some cases as a catalytic molecule. |

| I. | A represents a base pair where the plane of one base pair stacks over the other in the double helix giving the helix more stability in addition to hydrogen bonds. |
| II. | There are 10 base pairs in one complete turn of B-dNA. |
| III. | B is the backbone constituted by sugar-phosphate. |
| IV. | The two strands are parallel-oriented in the same direction with respect to each other. |
| V: | The diameter is uniform, around 2.0nm. |
