Here we will discuss the nucleotide monomer in detail. You guys have an idea about DNA and RNA as they are important genetic information carriers. We are referring to them here because nucleotides are one of the main parts of DNA and RNA. A nucleotide is an organic compound that consists of nucleoside and phosphate. Naturally, Nucleotides are found in the diet but they can be produced by the liver. It plays a central role in metabolism at a fundamental, cellular level. They provide chemical energy in the form of nucleotide triphosphate, adenosine triphosphate, and guanosine triphosphate. Let me tell you about the nucleotide monomer.  

What Is The Nucleotide Monomer 

A nucleotide monomer is a basic unit of DNA and RNA. Is nucleotide is a monomer? Yes, a nucleotide is the monomer of DNA and RNA. Nucleotides are composed of three subunit molecules namely nucleobase, a five-carbon sugar, and a phosphate group consisting of one to three phosphates. 

Describe the three structural components of an RNA nucleotide monomer. Let’s see it, the three parts consist of a nitrogenous base, a pentose sugar, and a phosphate group. 

The nitrogenous group base purine and pyrimidine are the two categories of nitrogenous bases. Guanine and Adenine are purines. Cytosine, thymine, and uracil are pyrimidines. 

Pentose sugar is sugar with 2-deoxyribose. In RNA, the sugar is ribose and it is 5-carbon sugar. The carbons are numbered one after another in order to keep track of where groups are attached. 

While talking about the phosphate group, it is PO4-3. The phosphorus atom is the central atom. A single atom of O2 is connected to the 5-C atoms in the sugar and to the phosphorus atoms. This is all about RNA nucleotide monomers. Now, you know about 3 structural components of an RNA nucleotide monomer

Now, the question is, is a nucleotide a monomer or polymer? A nucleotide is a monomer and not a polymer. 

Now, you know about the nucleotide monomer unit, let’s know about its properties, structure, and function.

Properties Of Nucleotide Monomer 

The properties of nucleotide monomer are, 

  • Nucleotide monomer consists of a five-carbon sugar, a nitrogen-containing base, and one or more phosphate groups. 
  • It is a relatively complete molecule that consists of three fundamental components namely, a nitrogen base, a sugar, and one phosphate group. 
  • Nucleotide monomer is a wide range of monomers required for specific cellular functions, such as information transfer or signaling processes within and between cells. 
  • They are in constant flux between their free and polymeric states.

Nucleotide Monomer Structure 

Now, you know that the nucleotide is the building block unit which means a monomer of DNA and RNA, but they also do a lot of other things. Nucleotide bases are of five chemical bases namely, Adenine, Cytosine, Guanine, Thymine, and Uracil. 

The base and the amount of phosphate residue determine how the compound is named. For instance, an Adenine nucleotide with one phosphate group is called adenosine monophosphate. Adenosine means Adenine, or the chemical base of the nucleotide, and monophosphate means one phosphate group. 

Adenine is a purine with the chemical formula C5H5N5. An Adenine-based nucleotide is called adenosine. Cytosine is a pyrimidine with the chemical compound C5H5N3O. A cytosine-based nucleotide is called a cytosine. Guanine is a purine with the chemical compound  C5H5N5O and Guanine-based nucleotide is called guanosine. Thymine is a pyrimidine with the chemical compound C5H6N2O2 and a thymine-based nucleotide is called a thymidine. 

Nucleotide Monomer Function 

Nucleotides can be used as a building block for nucleic acids that would go on to code for proteins, which are necessary for cell functions. Nucleotide makes proteins such as NAD and NADP, that are used in metabolism. They also create molecules such as cAMP, which are used in cell signaling. 

Facts About Nucleotide 

Here are some facts about nucleotides, 

  • Almost all nucleotides are derivatives of three heterocyclic compounds namely pyrimidine, purine, and pyridine. 
  • The most common nitrogen bases are pyrimidines, purines, and pyridine nicotinamide. 
  • Adenosine monophosphate or AMP is one of the components of RNA and also the organic component of the energy-carrying molecule ATP. 
  • A dinucleotide, nicotinamide adenine dinucleotide, participates in many oxidation reactions as an electron carrier, along with the related compound nicotinamide adenine dinucleotide phosphate.

What Do Nucleotide Monomers Make?

Nucleic acid polymer

Each nucleotide monomer, and therefore each nucleic acid polymer, is composed of a group of five elements. These elements bind to form monosaccharides, phosphate groups, and nucleobases, otherwise known as nitrogenous bases.

Is A Nucleotide Molecule A Monomer?

Nucleotides are monomers that join together to form the structural units of RNA and DNA, as well as providing an energy source in metabolism. (C), Guanine (G), Adenine (A), Thymine (T), and Uracil (U). A phosphate is a salt containing phosphorus and oxygen linked to one or more alkyl or aryl molecule.

Is Nucleotide Is The Monomer In DNA Or RNA?

Nucleotides. DNA and RNA are polymers (in the case of DNA, often very long polymers), and are made up of monomers known as nucleotides. When these monomers combine, the resulting chain is called a polynucleotide (poly- = “many”).

What Is Nucleotide Made Of?

A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).

Is ATP A Nucleotide Or Nucleoside?

The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups. ATP is commonly referred to as the “energy currency” of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups.

How Many Monomers Are In Nucleotides?

The monomers of the DNA are called nucleotides. Nucleotides are composed of four components- a base, deoxyribose sugar, and phosphate residue. DNA is composed of four types of monomers or nucleotides-

How Many Monomers Does RNA Have?

Chemists call the monomers “nucleotides.” The five pieces are uracil, cytosine, thymine, adenine, and guanine. No matter what science class you are in, you will always hear about ATCG when looking at DNA. Uracil is only found in RNA.


In this article, you have learned about the nucleotide monomer. A nucleotide is a structural monomer of nucleic acids, the hereditary-controlling components of all living cells. Nucleotides assist DNA and RNA in protein synthesis according to stored genetic information. And then the same genetic information gets transferred from one parent to their children in the form of traits. Nucleosides usually occur by chemical or enzymatic decomposition of nucleic acids. In the most important nucleotides, the sugar is either ribose or deoxyribose, and the nitrogen-containing compound is either pyrimidine or purine. So, this was all about the Nucleotide monomer
