Definition von oligonucleotide im Englisch Englisch wörterbuch: A short sequence of nucleotides (RNA or DNA), typically with twenty or fewer base pairs; a sequence of nucleotides, the building blocks of DNA; A DNA polymer composed of only a few nucleotides (See Nucleotide ); A short, defined sequence of nucleotides joined together in the typical phosphodiester linkage; a short sequence of nucleotides joined together; A molecule usually composed of 25 or fewer nucleotides; used as a DNA synthesis primer Source : Human Genome Project Information; PhRMA Genomics; A polymer consisting of a small number (about two to ten) of nucleotides; a molecule made up of a small number of nucleotides, typically fewer than 25 These are frequently used as DNA synthesis primers; A molecule consisting of a small number of nucleotide units; Oligonucleotide is a compound made up of the condensation of a small number of nucleotides; A molecule usually composed of 25 or fewer nucleotides; used as a DNA synthesis primer See also: nucleotide; a short sequence (usually 2-50 bases) of DNA Oligonucleotides of up to 30 bases are routinely synthesized from scratch for use as PCR primers or as probes for their sequence complements in a complex mixture of DNA; An oligomer resulting from a linear sequences of nucleotides [IUPAC Medicinal Chemistry] Macromolecules composed of short sequences of nucleotides that are usually synthetically prepared and used e g in site directed mutagenesis [IUPAC Bioinorganic]; A molecule usually composed of 25 or fewer nucleotides; used as a DNA synthesis primer Open reading frame (ORF) - Any stretch of DNA that potentially encodes a protein It begins with a start codon, and ends with a termination codon No termination codons may be present internally The identification of an ORG is the first indication that a segment of DNA may be part of a functional gene Operator - A site of gene regulation; a sequence of nucleotides recognized by a repressor protein Operon - A unit of transcription that consists of one or more structural genes, an operator and a promoter that function coordinately in bacterial gene expression Ortholog - Orthologs are genes in different species that evolved from a common ancestral gene by speciation Normally, orthologs retain the same function in the course of evolution Identification of orthologs is critical for reliable prediction of gene function in newly sequenced genomes; A short nucleic acid molecule, either obtained from an organism or synthesized chemically; {i} short chain of up to 20 nucleotides
