Nucleotide - Wikipedia
A nucleotide is composed of three distinctive chemical sub-units: a five-carbon sugar molecule, a nucleobase (the two of which together are called a nucleo side), and one phosphate group.

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 - 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 Definition, Structure, and Function
A nucleotide is an organic molecule made of a nitrogenous base, pentose sugar, and phosphate group. Nucleotides are ubiquitous in biology, serving as the foundation of genetic material and fulfilling other essential roles in cells. Take a look at what a nucleotide is, its structure, and its function in biological processes. What Is a Nucleotide?

Nucleotide | NIH
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. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the base uracil (U) takes the place of thymine. DNA and RNA molecules are polymers ...

NUCLEOTIDE Definition & Meaning - Merriam-Webster
The meaning of NUCLEOTIDE is any of several compounds that consist of a ribose or deoxyribose sugar joined to a purine or pyrimidine base and to a phosphate group and that are the basic structural units of nucleic acids (such as RNA and DNA).
