What Is A DNA Nucleotide?

A nucleotide is basically a chemical compound.  It consists of a heterocyclic base, a sugar, and one or more phosphate groups. Also they are bonded together with the help of cytosine. When looking at the most common nucleotides the base is a derivative of purine or pyrimidine.  The sugar is actually the pentose (five-carbon sugar) deoxyribose or ribose. Nucleotides are known as the monomers of nucleic acids, with three or more bonding together in order to form a nucleic acid.

Nucleotides are in effect the structural units of RNA, DNA, and several cofactors - CoA, FAD, FMN, NAD, and NADP. They play important roles in the cells and help with production of energy , metabolism, and signaling.
