The fundamental unit of nucleic acids. A nucleotide consists of a nitrogen-containing base attached to a pentose monosaccharide with one, two, or three phosphate groups attached by ester linkages to the saccharide moiety.
A subunit of DNA or RNA, it consists of nitrogenous base (adenine (A), guanine (G), thymine (T), or cytosine (C) in DNA; adenine (A), guanine (G), uracil (U), or cytosine (C) in RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA and ribose in RNA). Thousands of nucleotides are linked to form a DNA or RNA molecule. It is the sequence and number of nucleotides that determine the species and details of an organism.
Building blocks of DNA and RNA. Nucleotides are composed of phosphate, sugar and one of four bases, adenine, guanine, cytosine and uracil (RNA) or thymine (DNA). Three bases form a codon, which specifies a particular amino acid; amino acids are strung together to form proteins. Strings of thousands of nucleotides form a DNA or RNA molecule.
A cellular constituent that is one of the building blocks of ribonucleic acids (RNA) and deoxyribonucleic acid (DNA). In biological systems, nucleotides are linked by enzymes in order to make long, chainlike polynucleotides of defined sequence.

The structural unit of nucleic acids. A subunit of DNA or RNA consisting of purine bases (adenine, guanine), pyrimidine bases (thymine, or cytosine in DNA; uracil, or cytosine in RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA and ribose in RNA). Thousands of nucleotides are linked to form a DNA or RNA molecule.
Monomeric units from which DNA or RNA polymers are constructed. They consist of a purine or pyrimidine base, a pentose, and a phosphoric acid group. The nucleotides of DNA are deoxyadenylic acid, thymidylic acid, deoxyguanilic acid, and deoxycytidylic acid. Those of RNA are adenylic acid, uridylic acid, guanylic acid and cytidylic acid.
The monomeric unit that makes up the DNA or RNA, formed by a phosphate group, a pentose and one of the nitrogenous bases (A, T/U, C, G). Nucleotides in RNA are adenylate, guanylate, cytidylate and uridylate; in DNA, they are (d)adenylate, (d)guanylate, (d)cytidylate and thymidylate.

a component of nucleic acids containing a cyclic five-carbon sugar (ribose in RNA and deoxyribose in DNA), a purine (guanine or adenine) or pyrimidine (cytosine or uridine in RNA and thymidine in DNA) base attached to the 1'-carbon atom of the sugar and a phosphate attached to the 5'carbon of the sugar.
The basic chemical unit (monomer) in a nucleic acid. A nucleotide in RNA consists of one of four nitrogenous bases linked to ribose, which in turn is linked to phosphate. In DNA, deoxyribose is present instead of ribose.
The monomer of a nucleic acid. Nucleotides consist of (1) a phosphate group, a group of atoms containing phosphorus; (2) a sugar; and (3) a nitrogenous base, a compound containing nitrogen that removes H+ ions from solution. Nucleotides are grouped into two general classes, depending on the sugar group that they carry: deoxyribonucleic acids (DNA) contain the sugar deoxyribose and ribonucleic acids (RNA) contain the sugar ribose. Nucleotides are further divided by the type of nitrogenous base that they carry. DNA is composed of adenine, thymine, guanine, and cytosine. RNA is composed of adenine, uracil, guanine, and cytosine.

The molecular unit from which DNA and RNA are made. In DNA, a nucleotide consists of a 'base' [adenine (A), guanine (G), cytosine (C) or thymine (T)] linked to the sugar deoxyribose and a phosphate group. Many nucleotide units joined together via their sugar-phosphate groups make up a DNA molecule. In RNA, the sugar is ribose and the base thymine is replaced by uracil (U). The sequence of a DNA or RNA molecule is usually described as the sequence of its bases, e.g. AAAAGTTCGTCTAGGTC. A trinucleotide is a set of three nucleotides, e.g. CGG
Nucleic acid chains are composed of subunits called nucleotides. Nucleosides are related to nucleotides, the subunits of nucleic acids; however, nucleosides do not carry the phosphate groups of the nucleotides.

Nucleotides are the building blocks of nucleic acids, DNA, and RNA. Nucleotides are composed of phosphate groups, a five-sided sugar molecule (ribose sugars in RNA, deoxyribose sugars in DNA), and nitrogen-containing bases. These fall into two classes: pyrimidines and purines. A nucleotide without its phosphate group is called a nucleoside.

In DNA the sugar group is deoxyribose, while in RNA (a DNA-related molecule which helps to translate genetic information into proteins), the sugar group is ribose, and the base uracil substitutes for thymine. Each group of three nucleotides in a gene is known as a codon. A nucleic acid is a long chain of nucleotides joined together, and therefore is sometimes referred to as a "polynucleotide."

A nucleotide is a chemical compound that consists of a heterocyclic base, a sugar, and one or more phosphate groups. In the most common nucleotides the base is a derivative of purine or pyrimidine, and the sugar is the pentose (five-carbon sugar) deoxyribose or ribose. Nucleotides are the monomers of nucleic acids, with three or more bonding together in order to form a nucleic acid.
