Out of the following given choices;

contain ribose

consist of two strands

made of nucleotides

have an R group

The answer is 'made of nucleotides'. This is because out of the choices, DNA and RNA share the similarity of being made of nucleotides. However, while DNA is made of deoxyribose nucleotides, RNA is composed of ribose nucleotides. This difference is that in deoxyribose nucleotide, the 2nd carbon has a hydroxyl group while ribose nucleotide has hydrogen.
