Nucleotide vs. Nucleic Acid — What's the Difference?
By Tayyaba Rehman — Published on December 13, 2023
A nucleotide is the basic building block of nucleic acids. Nucleic acids, like DNA and RNA, are long chains of nucleotides. Thus, nucleotides are monomers, while nucleic acids are polymers.

Key Differences
A nucleotide is a compound consisting of a nucleoside linked to a phosphate group. Nucleic acid, on the other hand, is a chain-like molecule made up of a series of nucleotides.
Nucleotides are vital for several cellular processes and form the basic structural unit of nucleic acids such as DNA and RNA. Nucleic acid functions to carry genetic information in cells.
Each nucleotide in nucleic acids is made up of three parts: a sugar, a phosphate, and a nitrogenous base. Nucleic acid, as a chain of these nucleotides, showcases a sequence of bases, which carries the genetic code.
While a nucleotide can exist independently, nucleic acid is a collective term that describes long chains of individual nucleotides. This distinction is critical, as nucleotides serve as the foundation upon which nucleic acids are built.
In conclusion, a nucleotide is an individual unit, whereas nucleic acid is the complex structure formed by the alignment and connection of many nucleotides.
