Nucleotide - Definition, Structure (3 Parts), Examples & Function
WEBOct 4, 2019 · 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, …
Nucleotide Definition, Structure, and Function - Science Notes and …
WEBAug 31, 2023 · 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.
Nucleotide - Wikipedia
WEBNucleotides 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 - National Human Genome Research Institute
WEB5 days ago · Definition. 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).
Nucleotide | DNA, RNA & Polymerization | Britannica
WEBNucleotide, 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 nucleotides are of great importance to living organisms, as they are the building blocks of nucleic acids, the substances.
Nucleotide: Structure, Examples and Function - BYJU'S
WEBA 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. Nucleotides are essential for carrying out metabolic and physiological activities.

WEBNucleotide | Learn Science at Scitable. A single nucleotide contains a nitrogenous base (red), a deoxyribose sugar molecule (gray), and a phosphate group attached to the 5' side of the sugar...
Nucleic acids (article) | Khan Academy
WEBNucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in living organisms, all the way from single-celled bacteria to multicellular mammals like you and me.
Introduction to nucleic acids and nucleotides - Khan Academy
WEBDNA and RNA, composed of nucleotide building blocks, store hereditary information. These polymers have a backbone of alternating ribose and phosphate groups, with nitrogenous bases forming ladder rungs. The sequence of nucleotides encodes genetic information, making nucleic acids fundamental to life. Created by Sal Khan.
2.5: Nucleotides - Biology LibreTexts
WEBNucleotides, the building blocks of RNA and DNA, are themselves composed of a pentose sugar attached to a nitrogenous base on one side and a phosphate group on another. The sugar is either the 5-carbon sugar ribose or its close cousin, deoxyribose (the “deoxy” refers to a “missing” hydroxyl group on the 2-carbon, which has an H instead).
