Encyclopedia > GNA (nucleic acid)

GNA is glycol nucleic acid, a chemical similar to DNA or RNA but differing in the composition of its "backbone." GNA is not known to occur naturally in existing life on Earth. Ethylene glycol (IUPAC name:ethane-1,2-diol) is a chemical compound widely used as an automotive antifreeze (coolant). ... The general structure of a section of DNA Deoxyribonucleic acid (DNA) is a nucleic acid —usually in the form of a double helix— that contains the genetic instructions specifying the biological development of all cellular forms of life, and most viruses. ... Ribonucleic acid (RNA) is a nucleic acid polymer consisting of covalently bound nucleotides. ...


DNA and RNA have a deoxyribose and ribose sugar backbone, respectively, whereas GNA's backbone is composed of repeating glycol units linked by peptide bonds. The glycol molecule has just three carbon atoms and still shows Watson-Crick base pairing. Deoxyribose Deoxyribose, also known as D-Deoxyribose and 2-deoxyribose, is an aldopentose — a monosaccharide containing five carbon atoms, and including an aldehyde functional group. ... Ribose Ribose is a five carbon sugar (pentose) that is critical to living creatures. ... A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). ... General Name, Symbol, Number carbon, C, 6 Chemical series nonmetals Group, Period, Block 14, 2, p Appearance black (graphite) colorless (diamond) Atomic mass 12. ...
