DNA Internationally common abbreviation for the English term deoxyribonucleinacid. The German DNS (deoxyribonucleic acid) is hardly used any more to avoid confusion with the Domain Name System (DNS) of the internet. The structure of DNA was elucidated in 1953 by the biologists James Watson (*1928) and Francis Crick (1916-2004), who, together with Maurice Wilkins (1916-2004), were awarded the Nobel Prize for Medicine in 1962.

The name is derived from the basic DNA building blocks deoxyribose (a type of sugar consisting of five carbon atoms, a pentose), phosphoric acid and four bases, which make up the nucleic acid. DNA is a chain molecule in the cell nuclei of all plant, animal and human organisms that serves as a carrier of hereditary information for the maintenance of all biological life processes and is inherited. Genes are responsible for every single function in an organism, such as cell division or metabolism. However, they do not perform these functions directly, but have "service organs", so to speak, the proteins.

The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
