| recon | the smallest unit of DNA capable of recombination [recombination + Gr. on quantum] |
|---|---|
| HFR | high-frequency recombination |
| RAG | ragweed; recombination activating gene |
| REC | receptor; recombination, recombinant [chromosome] |
| RECA | recombination protein A |
| CF | Correction Factor |
|---|---|
| AC | attenuation correction |
| HR | Homologous recombination |
| RAG-1 | Recombination Activating Gene-1 |
| RAG | Recombination activating gene |
| aperture correction | <microscopy> An electronic process used in some high-resolution video cameras and monitors that compensates for the loss in sharpness of detail due to the finite dimensions (aperture) of the scanning beam. (05 Aug 1998) |
|---|---|
| correction | A setting right, as the provision of specific lenses for the improvement of vision or an arbitrary adjustment made in values or devices in performance of experimental procedures. Origin: L. Correctio = straightening out, amendment (18 Nov 1997) |
| correction collar | <microscopy> An adjustment collar provided on some high-numerical aperture, microscope objective lenses. Rotation of the collar adjusts the height of certain lens elements in the objective lens to compensate for variations in coverslip thickness or immersion media. at high numerical apertures, even a small deviation of the coverslip thickness (by as little as a few micrometres in some cases), or refractive index of the immersion medium from the designated standard, can introduce significant aberrations. (05 Aug 1998) |
| spontaneous correction of placenta previa | The upward "migration" of the placenta away from the internal os by the differential growth rates of upper and lower uterine segments. (05 Mar 2000) |
| occlusal correction | The correction of malocclusion, by whatever means is employed, elimination of disharmony of occlusal contacts. (05 Mar 2000) |
| genetic recombination | <molecular biology> Formation of new combinations of alleles in offspring (viruses, cells or organisms) as a result of exchange of DNA sequences between molecules. It occurs naturally, as in crossing over between homologous chromosomes in meiosis or experimentally, as a result of genetic engineering techniques. (18 Nov 1997) |
| recombination | <molecular biology> The creation, by a process of intermolecular exchange, of chromosomes combining genetic information from different sources, typically two genomes of a given species. Site specific, homologous, transpositional and nonhomologous illegitimate) types of recombination are known. 1st ed (18 Nov 1997) |
| recombination coefficient | <radiobiology> The rate of recombination of positive ions with electrons (or negative ions) in a gas, per unit volume, divided by the product of the particle densities of the two species (positive ions and electrons/negative ions) involved. (09 Oct 1997) |
| recombination fraction | The proportion of progeny of a mating pair of specific genotype and coupling phase that are recombinant; there must be no differential selection among the possible types of progeny, and the recombination fraction should be the same regardless of the alleles involved or their coupling phase. (05 Mar 2000) |
| recombination frequency | The frequency at which crossingover occurs between two chromosomal loci--the probability that twoloci will become unlinked during meiosis. (09 Oct 1997) |
| recombination, genetic | Production of new arrangements of genes by various mechanisms such as assortment and segregation, crossing over, gene conversion, transformation, conjugation, transduction, f-duction, or mixed infection of viruses. (12 Dec 1998) |
| recombination nodule | <molecular biology> Protein containing assemblies of about 90 nm diameter placed at intervals in the synaptonemal complexes that develop between homologous chromosomes at the zygotene stage of meiosis. Some nodules may be associated with the site of recombination. (18 Nov 1997) |
| recombination radiation | <physics> Radiation produced when a free electron in a plasma is captured by an ion. (09 Oct 1997) |
| mitotic recombination | <genetics, molecular biology> Somatic crossing over. Crossing over can occur between homologous chromosomes during mitosis, but is very rare because the chromosomes do not normally pair. When it occurs it can lead to new combinations of previously linked genes. Although infrequent, mitotic recombination has been utilised for genetic analysis in Aspergillus and in studies on developmental compartments in Drosophila where the frequency of mitotic recombination can be increased by X irradiation. (18 Nov 1997) |
| high frequency recombination strain | A type of bacterial strain which is able to pass on genetic information to neighboring bacteria at a high rate. The high-frequency recombination strain (Hfr) is able to do this because it possesses the f plasmid and can therefore initiate bacterial conjugation. (09 Oct 1997) |
