[Answer] What is the role RNA polymerase?

Answer: -binds to DNA during transcription and separates the DNA strands-then uses one strand of DNA as a template from which to assemble nucleotides into a complementary strand of RNA

What is the role RNA polymerase? Control of the process of gene transcription affects patterns of gene expression and thereby allows a cell to adapt to a changing environment perform specialized roles within an organism and maintain basic metabolic processes necessary for survival. Therefore it is hardly surprising that the activity of RNAP is long complex and highly regulated. In Escherichia coli bacteria more than 100 transcription factors have been identified which modify the activity of RNAP. General transcription factor - Wikipedia RNA polymerase - Wikipedia Thu Jan 09 2003 13:30:00 GMT-0500 (Eastern Standard Time) · RNA polymerase core enzyme binds to the bacterial general transcription (sigma) factor to form RNA polymerase holoenzyme and then binds to a promoter. ( RNA polymerase is called a holoenzyme when sigma subunit is attached to the core enzyme which is consist of 2 α subunits 1 β subunit 1 β' subunit only). Tue May 24 2005 14:30:00 GMT-0400 (Eastern Daylight Time) · A sigma factor is a protein needed only for initiation of RNA synthesis in bacteria. Sigma factors provide promoter recognition specificity to the RNA polymerase (RNAP) and contribute to DNA strand separation then dissociating from the RNA polymerase core enzyme following transcription initiation. The RNA polymerase core associates with the sigma factor to form RNA polymerase … Wed Oct 10 2001 14:30:00 GMT-0400 (Eastern Daylight Time) · Transcription is the process by which the information contained in a section of DNA is replicated in the form of a newly assembled piece of messenger RNA (mRNA). Enzymes facilitating the process include RNA polymerase and transcription factors.In eukaryotic cells the primary transcript is pre-mRNA.Pre-mRNA must be processed for translation to proceed. . Processing includes the … RNA byla poprvé izolována roku 1868 ve směsi s DNA F. Miescherem a nazvána nuklein nuklein byl ale původně považov...
