- 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
- 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 and Function in Genetics - Biology Insights
DNA nucleotides are the fundamental units of deoxyribonucleic acid, a molecule that stores and transmits genetic information across generations These nucleotides are distinguished by their unique nitrogenous bases: adenine, thymine, cytosine, and guanine
- 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
