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.
