⟩ Of what units are, nucleic acids constituted. What are the chemical entities that compose that unit?
Nucleic acids are formed by sequences of nucleotides.
Nucleotides are constituted by one molecule of sugar (ribose in DNA and deoxyribose in RNA) bound to one molecule of phosphate and to one nitrogen-containing base (adenine, uracil, cytosine, or guanine, in RNA, and adenine, thymine, cytosine, and guanine, in DNA).
