Spacer DNA — are regions of non transcribed DNA between tandemly repeated genes, such as ribosomal RNA genes in eukaryotes.Its function is probably to do with ensuring the high rates of transcription associated with these genes.The dNA sequence between genes … Wikipedia
spacer DNA — The DNA sequence between genes. In bacteria, only a few nucleotides long. In eukaryotes, can be extensive and include repetitive DNA, comprising the majority of the DNA of the genome. The term is used particularly for the spacer DNA between the… … Dictionary of molecular biology
Internal transcribed spacer — Als Ribosomale DNA (rDNA) werden jene Abschnitte der Desoxyribonukleinsäure (DNA) bezeichnet, die die Gene für ribosomale RNA (rRNA) enthalten. rRNA ist ein wichtiger Bestandteil der Ribosomen, in denen die Proteinsynthese (Translation)… … Deutsch Wikipedia
Nuclear localization sequence — A nuclear localization signal or sequence (NLS) is an amino acid sequence which tags a protein for import into the cell nucleus by nuclear transport. Typically, this signal consists of one or more short sequences of positively charged lysines or… … Wikipedia
Internal transcribed spacer — ITS (for internal transcribed spacer) refers to a piece of non functional RNA situated between structural ribosomal RNAs (rRNA) on a common precursor transcript. Read from 5 to 3 , this polycistronic rRNA precursor transcript contains the 5… … Wikipedia
Asthma spacer — An asthma spacer is a type of add on device used by an asthmatic person to increase the effectiveness of a metered dose inhaler. Such add on devices include spacers, which merely add space between the mouthpiece of the metered dose inhaler (MDI)… … Wikipedia
Repeated sequence (DNA) — In the study of DNA sequences, one can distinguish two main types of repeated sequence: Tandem repeats: Satellite DNA Minisatellite Microsatellite Interspersed repeats: SINEs (Short Interspersed Nuclear Elements) LINEs (Long Interspersed Nuclear… … Wikipedia
intergenic spacer — Abbreviation: IGS Non coding DNA separating tandemly arranged copies of a repeated gene sequence (typically ribosomal DNA). Of particular interest because, unlike the coding sequence itself, the spacers show high levels of interspecific sequence… … Glossary of Biotechnology
internal transcribed spacer — Abbreviation: ITS Non coding regions separating the individual components of the ribosomal DNA units. These regions show much more sequence polymorphism than the genic regions themselves, and therefore, like the intergenic spacers, are useful a… … Glossary of Biotechnology
Ribosome display — is a technique used to perform in vitro protein evolution to create proteins that can bind to a desired ligand. The process results in translated proteins that are associated with their mRNA progenitor which is used, as a complex, to bind to an… … Wikipedia
