It is a technique used in genetic studies that allows the detection and quantification of mRNA [messenger ribonucleic acid] It is a very sensitive method that shows whether or not a specific gene is being expressed in a given sample. RT-PCR is a very important test in the field of Genetically-Modified Organisms (GMO's) because it gives researchers a mechanism to test whether any specific gene is turned on (active) or turned off (inactive). This allows researchers to identify the benefits of genetically-modified organisms with respect to their "natural" counterparts and search for any significant differences in which genes are expressed in the two types of organisms. 3, record 1, English, - reverse%20transcription%2Dpolymerase%20chain%20reaction

La PCR et la RT-PCR(reverse transcriptase PCR) permettent la synthèse de millions de copies d’un segment spécifique d’ADN ou d’ARN(après une étape de transcription inverse permettant la synthèse d’un ADNc), grâce à une succession de réactions se faisant à différentes températures : dénaturation de l'ADN cible par rupture des liaisons hydrogène à 94° C, hybridation des amorces sur une séquence complémentaire d’un des brins d’ADN au niveau 3’(entre 37 °C et 68 °C), élongation(à 72 °C le plus souvent) grâce aux dNTP ajoutés dans le milieu réactionnel et à une enzyme thermostable à activité ADN polymérase(Taq polymérase). 3, record 1, French, - m%C3%A9thode%20PCR%2DCDNA

Simply put, an array is an orderly arrangement of samples. An array experiment can make use of common assay systems such as microplates or standard blotting membranes, and can be created by hand or make use of robotics to deposit the sample. In general, arrays are described as macroarrays or microarrays, the difference being the size of the sample spots. Macroarrays contain sample spot sizes of about 300 microns or larger and can be easily imaged by existing gel and blot scanners, such as Storm, FluorImager, or Personal Densitometer. The sample spot sizes in microarrays are typically about 200 microns in diameter or smaller and these arrays usually contains thousands of spots. 3, record 7, English, - macroarray

Les méthodes les plus récentes sont celles des «microarrays» et des puces à oligonucléotides ou «oligochips»(les puces à ADN proprement dites). Un «microarray» comporte quelques milliers de gènes représentés par des produits de PCR qu'a déposé un robot «ad hoc» sur une lame de verre traitée; l'hybridation est effectuée avec une sonde complexe obtenue par rétrotranscription du mélange ARN en présence de nucléotides substitués autorisant une détection ultérieure(directe ou non) par fluorescence. L'acquisition des résultats est généralement effectuée par système de balayage laser équipé d’une optique confocale, les signaux étant mesurés par un photomultiplicateur. 2, record 7, French, - jeu%20ordonn%C3%A9%20de%20macro%C3%A9chantillons
