The nucleotides used to build DNA are Adenine, Cytosine, Guanine, and Thymine. For RNA, there is no Thymine; it is replaced with another nucleotide called Uracil. These are actually the names of the nitrogenous bases that nucleotides contain.A nucleotide is made up of a Deoxyribose Sugar, a Phosphate Molecule, and a Nitrogenous Base. We refer to them though by the name of their nitrogenous base.hese are actually the names of the nitrogenous bases that nucleotides contain.

DNA is an example of a macromolecule, i.e. a large molecule with a special shape, which is built up from many smaller parts called sub-units. If you could magnify part of a nucleus, you would see the DNA molecule looking like a twisted rope ladder - a double helix. The two strands forming the sides of the ladder give it a strong yet flexible structure, which does not vary along its length. Stretched between these are the rungs of the ladder, the parts of the DNA molecule which vary, and so the differences carry genetic information. These parts are made up of sections called bases, which fit together in pairs
