Detailed explanation-1: -Nucleotides, as they appear in RNA, contain on average 36.2% C, 16% N, and 9.6% P; the elemental composition of nucleotides in DNA is very similar. Thus, nucleotides in nucleic acids have N levels that are similar to those found in protein (16% vs. 17%), which are in turn much higher than levels in most organisms.
Detailed explanation-2: -The five elements necessary to construct a nucleic acid chain are carbon, hydrogen, oxygen, nitrogen, and phosphorus. The addition of phosphorus makes nucleic acid different to other categories of biocompounds, namely carbohydrates, lipids, and proteins.
Detailed explanation-3: -Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.
Detailed explanation-4: -Deoxyribonucleic acid | C15H31N3O13P2-PubChem.
