Which component is common to both DNA and RNA nucleotides?

Explanation:
Nucleotides in both DNA and RNA share a phosphate group that forms the backbone of the polymer by linking to the sugar of the neighboring nucleotide through phosphodiester bonds. This phosphate component is present in every nucleotide, making it common to both molecules, whereas the sugar differs (DNA uses deoxyribose, RNA uses ribose) and the bases differ (DNA includes thymine; RNA uses uracil). So the phosphate group is the feature shared by DNA and RNA nucleotides.
