WebThe synthesis of RNA is performed by enzymes called RNA polymerases. In higher organisms there are three main RNA polymerases, designated I, II, and III (or sometimes A, B, and C). Each is a complex protein consisting of many subunits. RNA polymerase I synthesizes three of the four types of rRNA (called 18S, 28S, and 5.8S RNA); therefore it … WebWhich of the comparisons between DNA polymerase and RNA polymerase is false? -Both DNA polymerase and RNA polymerase have proofreading activity. -DNA polymerase requires an additional enzyme to unwind double-stranded DNA molecules, but RNA polymerase does not. -Both DNA and RNA polymerase catalyze the addition of …

RNA Polymerase: Function and Definition

Webcould 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. WebThe RNA polymerase III IgG ELISA tests only for the RP155 dominant epitope, other epitopes in the antigenic complex are absent and cannot be detected. (6) The overall pooled prevalence of anti-RNAP polymerase III antibody is reported to be 11%, 95% confidence interval: 8 to 14, range of 0 to 41% in published studies. (4)
