Nucleic acid is a general term for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). It is a biomacromolecule compound polymerized from many nucleotide monomers, and it is one of the most basic substances in life.
Biological macromolecules polymerized from many nucleotides are one of the most basic substances in life. It was first discovered by Michel in 1868 and isolated from pus cells. Nucleic acids are widely found in all animals, plant cells and microorganisms, and they often combine with protein to form nucleoproteins. Different nucleic acids have different chemical compositions and nucleotide sequences. According to different chemical compositions, nucleic acids can be divided into RNA and deoxyribonucleic acid, or DNA.
