Nucleotide | biochemistry | Britannica.com
Nucleotide: Nucleotide, 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 | Definition of Nucleotide by Merriam-Webster
Nucleotide definition 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).
Nucleotide excision repair - Wikipedia
Nucleotide excision repair is a DNA repair mechanism. DNA damage occurs constantly because of chemicals (e.g. intercalating agents), radiation and other mutagens.Three excision repair pathways exist to repair single stranded DNA damage: Nucleotide excision repair (NER), base excision repair (BER), and DNA mismatch repair (MMR). While the BER pathway can recognize specific non-bulky lesions in ...
Nucleotide - Wikipedia
A nucleotide is composed of three distinctive chemical sub-units: a five-carbon sugar molecule, a nitrogenous base—which two together are called a nucleoside—and one phosphate group.With all three joined, a nucleotide is also termed a "nucleoside monophosphate".The chemistry sources ACS Style Guide and IUPAC Gold Book prescribe that a nucleotide should contain only one phosphate group, but ...
Welcome to NENUN. NENUN is the “Nordic Environmental Nucleotide Network”. We are a group of more than 20 laboratories in the Nordic Countries which work with Molecular Microbial Ecology in various settings like soil, freshwater, groundwater, deep ocean floor etc.
Complementary Nucleotide Bases | Science Primer
DNA * is the information molecule of the cell. DNA’s capacity to store and transmit heritable information depends on interactions between nucleotide bases and on the fact that some combinations of bases form stable links, while other combinations do not. Base pairs that form stable connections are called complementary bases.
Nucleic Acids - Function, Examples, and Monomers
Nucleic acids are molecules that allow organisms to transfer genetic information from one generation to the next. These macromolecules store the genetic information that determines traits and makes protein synthesis possible.

International Nucleotide Sequence Database Collaboration ...
The International Nucleotide Sequence Database Collaboration (INSDC) is a long-standing foundational initiative that operates between DDBJ, EMBL-EBI and NCBI.INSDC covers the spectrum of data raw reads, though alignments and assemblies to functional annotation, enriched with contextual information relating to samples and experimental configurations.
