Question

Of what units are nucleic acids comprised? Write down the chemical entities which compose that unit?

Answer 1

Nucleic acids are formed by series of nucleotides. Nucleotides are comprised by one molecule of sugar (deoxyribose in the DNA and ribose in the RNA) bound out to one molecule of phosphate as well as to one nitrogen-containing base (adenine, cytosine, uracil or guanine, in RNA, and cytosine, thymine, adenine as well as guanine, in the DNA).
