A nucleotide is an organic molecule consisting of a heterocyclic nucleobase (a purine or a pyrimidine ), a pentose sugar (deoxyribose in DNA or ribose in RNA ), and a phosphate or polyphosphate group. (A nucleoside is similar, except that it contains only the sugar and base, without a phosphate.)
monomers of nucleic acids and also play important roles in cellular energy transport and transformations (notably ATP and NAD+/NADH ) and in enzyme regulation (see for example, protein kinase ).

Nucleotide - Wikipedia, the free encyclopedia (551 words)
A nucleotide is a chemical compound that consists of a heterocyclic base, a sugar , and one or more phosphate groups . In the most common nucleotides the base is a derivative of purine or pyrimidine , and the sugar is the pentose (five-carbon sugar ) deoxyribose or ribose . Nucleotides are the structural units of RNA , DNA , and several cofactors - CoA , FAD , FMN , NAD , and NADP .
Nucleotide (337 words)
A nucleotide is the monomer structural unit of nucleotide chains that form the nucleic acids RNA and DNA , as well as several lesser nucleic acids. Nucleotides code for proteins and enzymes as well as determine the genetic structure of life. Nucleotides are also crucial for cellular energy transportation and transformation and in the regulation of enzymes .
