NUC-1031 [Supplementary Concept]
structure in first source
Date introduced: April 27, 2014
Ribonucleotides
Nucleotides in which the purine or pyrimidine base is combined with ribose. (Dorland, 28th ed)
Year introduced: 1973(1971)
Pyrimidines
A family of 6-membered heterocyclic compounds occurring in nature in a wide variety of forms. They include several nucleic acid constituents (CYTOSINE; THYMINE; and URACIL) and form the basic structure of the barbiturates.
Year introduced: THONZYLAMINE was heading 1972-1984 (Prov 1972)
Pyrimidine Nucleotides
Pyrimidines with a RIBOSE and phosphate attached that can polymerize to form DNA and RNA.
Year introduced: 1974(1972)
Nucleotides
The monomeric units from which DNA or RNA polymers are constructed. They consist of a purine or pyrimidine base, a pentose sugar, and a phosphate group. (From King and Stansfield, A Dictionary of Genetics, 4th ed)
Nucleic Acids, Nucleotides, and Nucleosides
Complex compounds of high molecular weight occurring in living cells. These are basically of two types, ribonucleic (RNA) and deoxyribonucleic (DNA) acids, both of which consist of nucleotides (nucleoside phosphates linked together by phosphate bridges).
Year introduced: 1998
Heterocyclic Compounds, 1-Ring
Organic compounds that contain a ring structure made up of carbon and one or more additional elements such as nitrogen and oxygen.
Heterocyclic Compounds
Cyclic compounds that include atoms other than carbon in their ring structure.
Cytosine Nucleotides
A group of pyrimidine NUCLEOTIDES which contain CYTOSINE.
