RNA-Polymerase


RNA-Polymerase
RNA-Polymerase, DNA-abhängiges Enzym, das bei der Transkription mRNA synthetisiert. Die R. entwindet den DNA-Doppelstrang, lagert in 5'→3'-Richtung komplementäre Nucleotide an den codogenen DNA-Einzelstrang an und verbindet sie zu einem RNA-Einzelstrang. Prokaryoten haben eine R., Eukaryoten drei verschiedene.
