What DNA components do all the nucleotides of the
organisms have in common?

All nucleotides have a common structure its a phosphate group linked by a phosphoester bond to a pentose

Explanation:

All nucleotides have a common structure: a phosphate group linked by a phosphoester bond to a pentose (a five-carbon sugar molecule) that in turn is linked to an organic base (Figure 4-1a). In RNA, the pentose is ribose; in DNA, it is deoxyribose (Figure 4-1b).
