Nucleotide - Wikipedia
Nucleotides are organic molecules composed of a nitrogenous base, a pentose sugar and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth.

Nucleotide | Description, Types, Function, & Facts | Britannica
A nucleotide is any member of a class of organic compounds in which the molecular structure comprises a nitrogen-containing unit (base) linked to a sugar and a phosphate group.

The Nucleotide database is a collection of sequences from several sources, including GenBank, RefSeq, TPA and PDB. Genome, gene and transcript sequence data provide the foundation for biomedical research and discovery.

Nucleotide Definition, Structure, and Function
What Is a Nucleotide? A nucleotide is an organic molecule that serves as the building block for nucleic acids like DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). These molecules consist of three primary components: a nitrogenous base, a sugar molecule, and one or more phosphate groups.

Nucleotide - National Human Genome Research Institute
A nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.

Nucleotide: Structure, Types, and Biological Functions
A nucleotide is a pentose sugar linked to a nitrogenous base and a phosphate molecule. Nucleotides are the building blocks of DNA. Figure: Nucleotide. The nitrogenous bases are derived from two-parent compounds – purines and pyrimidines.

Nucleotide Structure – What does a nucleotide look like? - BYJU'S
A nucleotide is an organic molecule with a basic composition of a nitrogenous base, pentose sugar and phosphate. DNA and RNA are polynucleotides, which contain a chain of nucleotides monomers with different nitrogenous bases.

What are Nucleotides? - Creative Proteomics
Nucleotides are organic molecules that serve as the building blocks of nucleic acids, such as DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). They are composed of three primary components: a nitrogenous base, a five-carbon sugar, and one or more phosphate groups.

13.2: Nucleotides - The Building Blocks of Nucleic Acids
Describe the makeup of nucleotides that are building blocks of nucleic acids DNA and RNA. Nucleic acids are biopolymers that carry the codes for the synthesis of proteins and pass them on from generation to generation, i.e., they are genetic materials.

Definition of nucleotide - NCI Dictionary of Genetics Terms
A nucleotide is made up of a nitrogen-containing base (adenine, guanine, thymine, and cytosine in DNA, and adenine, guanine, uracil, and cytosine in RNA), a phosphate group, and a sugar molecule (deoxyribose in DNA, and ribose in RNA). DNA and RNA are polymers made up of many nucleotides.
