WebFeb 27, 2024 · Properties. RNA polymerase reads the template DNA as 3′ to 5′ but synthesis the polynucleotide in a 5′ to 3′ direction. RNA polymerase does not have nucleases … RNA polymerase binding in bacteria involves the sigma factor recognizing the core promoter region containing the −35 and −10 elements (located before the beginning of sequence to be transcribed) and also, at some promoters, the α subunit C-terminal domain recognizing promoter upstream elements. There are multiple interchangeable sigma factors, each of which recognizes a distinct se…

WebReplication of the hepatitis C viral genome is catalyzed by the NS5B (nonstructural protein 5B) RNA-dependent RNA polymerase, which is a major target of antiviral drugs currently in the clinic. Prior studies established that initiation of RNA replication could be facilitated by starting with a dinucleotide (pGG). WebLike prokaryotic cells, and transcription of genes in eukaryotes req the action of one RNA polymerase to bind to a DNA sequence upstream to an gene for order to initiate transcription. However, unlike prokaryotic measuring, the eucaryal RNA polymerase requires others murine, alternatively transcription factors, to facilitate transcription initiation. pumpkin shannon net worth
