Internationally common abbreviation for the English term Deoxyribonucleic acid. The German term DNS (Desoxyribonukleinsäure) is hardly used anymore to avoid confusion with the Domain Name System (DNS) of the Internet. The structure of DNA was elucidated in 1953 by biologists James Watson (*1928) and Francis Crick (1916-2004), who received the Nobel Prize for Medicine in 1962 along with Maurice Wilkins (1916-2004).

The name derives from the initial letters of the DNA building blocks Deoxyribose (a type of sugar consisting of five carbon atoms), phosphoric acid, and four bases that make up the nucleic acid. DNA is a chain molecule found in the cell nuclei of all plant, fungal, animal, and human organisms, serving as a carrier of hereditary information for maintaining all biological life processes and is inherited. Genes are responsible for each individual function in an organism, such as cell division or metabolism.

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
