Detailed explanation-1: -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-2: -Nucleic acids are made of nitrogen-containing bases, phosphate groups, and sugar molecules. Each type of nucleic acid has a distinctive structure and plays a different role in our cells.

Detailed explanation-3: -Both interactions are of equal importance in nucleic acids. The two strands of a DNA molecule are held together by the hydrogen bonding between the related bases. Adenine can form two hydrogen bonds with thymine and cytosine can form three hydrogen bonds with guanine (Fig. 1).

Detailed explanation-4: -Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).

Detailed explanation-5: -Another name for Nucleic acids are also called nitrogen bases. The structure of the bases also includes common organic atoms such as carbon, oxygen and hydrogen. The outside of the DNA structure also includes phosphorus.
