Nucleotides. A single nucleotide contains a phosphate group, deoxyribose or ribose (depending on the nucleic acid) and a nitrogen base, which can be adenine, guanine, cytosine â¦ , thymine, and uracil. These monomers combine to form polymers known as DNA or RNA.
A DNA strand is made up of hundreds of thousands of nucleotides put together. A nucleotide is a type of molecule (organic molecule, to be specific) that is made up of a phosphate, a sugar, and a nitrogen base. In all DNA nucleotides, there is always the same phosphate and sugar. But the nitrogen bases differ. There are four nitrogen bases in DNA--Adenine, Guanine, Cytosine, and Thymine.
