A scientific graphic comparing DNA and RNA molecular structures on a light background within a black-bordered panel. On the left, a double helix labelled DNA (Deoxyribonucleic Acid) shows base pairs and the sugar-phosphate backbone. On the right, a single-stranded RNA (Ribonucleic Acid) structure is shown. Along both sides are chemical diagrams of nitrogenous bases in coloured boxes: Cytosine (yellow), Guanine (green), Adenine (blue), Thymine (red) and Uracil (purple), with a note that Uracil replaces Thymine in RNA. No people are visible.
