DNA stands for deoxyribonucleic acid. The deoxy- in the DNA is a short term for deoxyribose. The nucleic acid molecule has three parts; sugar, phosphate and a base. The phosphate in the DNA acts as a backbone of the molecule. It is also responsible for the DNA’s ‘double-helix’ structure. The base has four codes that create the DNA. And the sugar is deoxyribose for DNA. Hydrogen bonding is an ionic bonding between molecules, it is not a sugar. Nitrogenous is also not a sugar.
