    nucleic acid, naturally occurring chemical compound that serves as the main information-carrying molecule of the cell and that directs the process of protein synthesis, thereby determining the inherited characteristics of every living thing.

  3. A nucleic acid is a chain of nucleotides which stores genetic information in biological systems. It creates DNA and RNA, which store the information needed by cells to create proteins. This information is stored in multiple sets of three nucleotides, known as codons.

  4. Nucleic acid - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid

    Nucleic acids are large biomolecules that are crucial in all cells and viruses. [1] They are composed of nucleotides, which are the monomer components: a 5-carbon sugar, a phosphate group and a nitrogenous base. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

    A nucleic acid is a biomolecule that stores and transmits genetic information in living organisms. Nucleic acids are composed of nucleotides, which, in turn, are made up of sugar, phosphate group, and nitrogenous base. There are two types of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
