Nucleotide | Definition of Nucleotide by Merriam-Webster
: 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) — compare nucleoside
Deoxyribose | chemical compound | Britannica.com
Deoxyribose: Deoxyribose, five-carbon sugar component of DNA (q.v.; deoxyribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the DNA polymer and binds to nitrogenous bases. The presence of deoxyribose instead of ribose is one difference between DNA and RNA (ribonucleic acid).
EMBOSS Water < Pairwise Sequence Alignment < EMBL-EBI
EMBOSS Water uses the Smith-Waterman algorithm (modified for speed enhancements) to calculate the local alignment of two sequences. This is the form for nucleotide sequences.
Glossary | GMO Answers
Amino Acid. Amino acids are the building blocks of proteins.There are 20 different amino acids, and each one has a unique and specific chemical group, which gives it distinctive properties.
EMBOSS Needle < Pairwise Sequence Alignment < EMBL-EBI
EMBOSS Needle reads two input sequences and writes their optimal global sequence alignment to file. This is the form for nucleotide sequences.
Nucleotide salvage - Wikipedia
A salvage pathway is a pathway in which nucleotides (purine and pyrimidine) are synthesized from intermediates in the degradative pathway for nucleotides.. Salvage pathways are used to recover bases and nucleosides that are formed during degradation of RNA and DNA.This is important in some organs because some tissues cannot undergo de novo synthesis.. The salvaged bases and nucleosides can ...
Guanine nucleotide exchange factor - Wikipedia
Guanine nucleotide exchange factors (GEFs) are proteins or protein domains that activate monomeric GTPases by stimulating the release of guanosine diphosphate (GDP) to allow binding of guanosine triphosphate (GTP). A variety of unrelated structural domains have been shown to exhibit guanine nucleotide exchange activity. Some GEFs can activate multiple GTPases while others are specific to a ...
Single nucleotide polymorphism (SNP) detection and ...
A Single nucleotide polymorphism or SNP (pronounced snip) is a DNA sequence variation occurring when a single nucleotide - A, T, C, or G - in the genome (or other shared sequence) differs between members of a species (or between paired chromosomes in an individual).
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.
DNA: Definition, Structure & Discovery | What Is DNA?
The structure of DNA and RNA. DNA is a double helix, while RNA is a single helix. Both have sets of nucleotides that contain genetic information.
