In a CFD, the unipolar input signal is turned into a bipolar signal by an appropriate electronic chain. This is done by splitting the input signal with different ratio. One of the signals experiences a certain delay and gets inverted, while the other gets attenuated. Finally both signals are again added to form the CFD bipolar signal. 4, record 1, English, - constant%20fraction%20discriminator

Le discriminateur à fraction constante. Pour une fenêtre d’énergie réglée, soit sur 1,28 MeV [mégaélectronvolt], soit sur 511 keV [kiloélectronvolts], il génère une impulsion logique suivant le principe de discrimination à fraction constante pour dater la détection du gamma indépendamment de la forme de l’impulsion envoyée par le photomultiplicateur. Plus précisément, le signal de sortie du photomultiplicateur est divisé en deux parties; la première est retardée et inversée et la deuxième est atténuée d’une fraction constante. Les deux signaux sont ensuite additionnés pour former un signal bipolaire caractérisé par un passage à zéro temporellement indépendant de l’amplitude du signal initial. 3, record 1, French, - discriminateur%20%C3%A0%20fraction%20constante

Short stretches of RNA have been found attached to the 5’ ends of many newly synthesized DNA chains. The starting points for DNA replication may therefore be recognized not by a DNA polymerase, but by a form of RNA polymerase. Following binding of a starter RNA polymerase, a number of ribonucleotides are sequentially linked together until a stop signal is read. The enzyme then detaches leaving a short RNA chain still bound to its DNA template. This RNA chain then serves as a primer onto which DNA polymerase III adds deoxynucleotides. Removal of the RNA primer occurs later through the action of other enzyme(s) which can digest away the RNA component of RNA/DNA hybrids. One enzyme that has this capacity is DNA polymerase I, whose primary task may be to close the gaps between RNA-primed DNA fragments. 1, record 4, English, - RNA%2Dprimed%20DNA%20fragment

On a trouvé de courts fragments d'ARN attachés aux extrémités 5' de nombreuses chaînes d'ADN nouvellement synthétisées. Les points de départ de la réplication de l'ADN pourraient donc être reconnus non pas par une ADN polymérase mais par une forme d'ARN polymérase. Après l'attachement d'une ARN polymérase de démarrage, un certain nombre de ribonucléotides sont séquentiellement liés les uns aux autres jusqu'à lecture d'un signal stop. L'enzyme se détache alors, laissant une courte chaîne d'ARN toujours liée à sa matrice ADN. Cette chaîne d'ARN sert alors d'amorce à laquelle l'ADN polymérase III ajoute des désoxynucléotides. Cet ARN amorce est éliminé plus tard par l'action d'autres enzymes (ou d'une autre enzyme) qui sont capables de digérer la partie ARN de l'hybride ARN/ADN. Une enzyme qui possède cette aptitude est l'ADN polymérase I, dont le rôle principal consiste à combler les espaces entre les fragments d'ADN amorcés par des ARN. 1, record 4, French, - fragment%20d%27ADN%20amorc%C3%A9%20par%20des%20ARN
