WebbSpecifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand. Stages of transcription Transcription of a gene takes place in three stages: initiation, elongation, and termination. Here, we will briefly see how these steps happen in bacteria. WebbSedan vandrar RNA-polymeraset längs med genen, med cirka 20 nukleotider i sekunden, och styr tillverkningen av budbärar-RNA som är komplementärt till genen. När genen …

WebbRNA-polymerase is verantwoordelijk voor de transcriptie. Het enzym loopt in de 5’-3’ richting en is dus complementair met de 3’-5’ richting op de anti-sense DNA streng. Na transcriptie zal de enkelstreng worden vrijgesteld en komen de DNA-sense en anti- sense streng weer bij elkaar. WebbRNA-Polymerasen sind Proteinkomplexe, die als Enzyme beim Aufbau des strangförmigen Polymers einer Ribonukleinsäure aus ihren Grundbausteinen mitwirken. Diese aus …

Zo’n plaats in het DNA heet de promotor. De promotor ligt voor het gen dat afgeschreven gaat worden. De herkenning van de promotor vindt plaats door bepaalde DNA-bindende eiwitten: de sigmafactor in prokaryoten en transcriptiefactoren in eukaryoten.
