Question

Of what units are nucleic acids composed of? Describe the chemical entities which include that unit?

Answer 1

Nucleic acids are made by sequences of nucleotides.

Nucleotides are comprised by one molecule of sugar (that is, deoxyribose in DNA and ribose in RNA) bound to one molecule of phosphate and to one nitrogen having base (uracil, adenine, cytosine or guanine, in RNA, and adenine, thymine, guanine and cytosine in DNA).
