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 - Definition, Structure (3 Parts), Examples & Function
A nucleotide is an organic molecule that is the building block of DNA and RNA. They also have functions related to cell signaling, metabolism, and enzyme reactions. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.

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 | 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.

Nucleotide Definition, Structure, and Function - Science Notes and Projects
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, Examples and Function - 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.

12+ Insights On Nucleotides: The Building Blocks Of Life Explained
Nucleotide Synthesis and Repair: Maintaining Genetic Integrity The synthesis of nucleotides is a tightly regulated process that ensures the availability of these molecules for DNA and RNA production. Nucleotides can be synthesized de novo (from simple precursors) or through salvage pathways that recycle existing nucleotides.

What is Nucleotide? Definition, Properties, Components & Functions ...
Nucleotides can define as the monomer units which unites by 3’-5’ phosphate bridges to form a “Nucleic acid” i.e. DNA or RNA. In this content definition, characteristics, components, nomenclature and function of nucleotide are explained.

Nucleotide: Structure, Types, and Biological Functions - Microbe Notes
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.
