Nucleic Acid

United States

Nucleic acids are the principle genetic materials of all living organisms. They are complex macromolecule containing carbon, hydrogen, oxygen, nitrogen and phosphorous. Living organisms contain nucleic acid in the form of deoxyribonucleic acid (DNA) and ribonucleic acid(RNA). Some viruses contain only RNA(viroids) e.g. TMV(tobacco mosaic Virus) , poliomyelitis virus. Some viruses contain DNA only ex: bacteriophages, Vaccinia and Adenoviruses. In bacteria and higher cells both types of nucleic acids are found. The nucleic acids was first isolated in 1868 by miescher from a nuclei of pus cells on hospital bandages. He called it nuclei. He showed that the nuclein contained phosphorus, carbon, oxygen, hydrogen and nitrogen. Fischer (1880) identified that the Nucleic contains two types of nitrogenous bases and they are purines and pyrimidines. Altmann (1889) gave the term nucleic acid to replace nuclein. The name nucleic acid was given to it due too its acidic property. Levene identified a five-carbon sugar ribose in 1910. He later discovered that there was another type of nucleic acid, which contains deoxyribose. Nucleic acid that contains ribose sugar is called the ribonucleicacid (RNA) and that which contains deoxysugar named as the deoxyribonucleic acid. He also suggested that phosphorus is present in nucleic acid as a phosphate group. Upon hydrolysis, Nucleic acids yield 3 components namely phosphoric acid, a pentose sugar and nitrogenous bases.

University of Southern Denmark: Nucleic Acid Center

NAC (Nucleic Acid Center) is a Research Center established in 2001, based on fundings from The Danish National Research Foundation for studies on Nucleic Acid Chemical Biology. The idea of the research center was to combine synthetic organic chemistry and the encoded recognition pattern of nucleic acids in novel innovative and creative ways. The research center is located at the University of Southern Denmark, Odense, at the Department of
