WebIn the process of transcription (by any polymerase), there are three main stages: Initiation: the construction of the RNA polymerase complex on the gene's promoter with the help … WebThe flow of information follows a conventional pathway: dsDNA → mRNA → protein, with a DNA-dependent RNA-polymerase producing the mRNA and the host ribosome producing the protein. The genome replication, dsDNA → dsDNA, requires a DNA-dependent DNA-polymerase from either the virus or the host cell. dsDNA. can 501c3 be a private corporationWebcould the definition of that term be changed to make it clear that it includes bacterial-type RNA polymerase. I saw GO:0006357 but didn't think it was appropriate because it appears to be specific for RNA pol II which is a eukaryote-specific term. I can see that there are some molecular function terms specific for bacterial-type RNA polymerase eg. can 514 be divided by 4

"Web19 okt. 2010 · 1. One Strand is Template for RNA polymerase. For any one gene or region, RNA polymerase uses Crick or Watson, but not both, as template. RNA that is made is complementary (and antiparallel) to the template strand. Note that an entire strand is not used as template throughout. " - How is rna polymerase made
