During the transcription, RNA polymerase opens the double-stranded DNA so that one DNA strand can be used as a template for the process of synthesizing a mRNA molecule. The main difference between prokaryotic and eukaryotic RNA polymerase is that prokaryotes have a single type of RNA polymerase, whereas eukaryotes have three main types of RNA polymerases. This polymerase is the most studied type and required transcription factors that bind …

The official name of RNA polymerase is the DNA-directed RNA polymerase. Slight differences are found between different types of RNA polymerase, and eukaryotes even have several different versions which process different parts of the DNA. • DNA polymerase starts to function from a 3’ end of the DNA strand, while RNA polymerase can start to function at anywhere of the DNA strand from 3’ end to 5’ end direction. When the new Okazaki fragment is complete, the RNA primer is removed by DNA polymerase-I and is replaced with DNA by the sea enzyme. RNA polymerase is a high molecular weight enzyme.
• RNA polymerase forms a variety of products but not the DNA polymerase. Furthermore, prokaryotic RNA polymerase contains five subunits while in eukaryotes, RNA polymerase I transcribes rRNA genes, RNA polymerase II transcribes mRNA genes, and RNA polymerase III … In cell: RNA synthesis …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 … RNA polymerase III transcribes AT-rich dsDNA into an RNA-containing 5′-triosphate moiety which can then be recognized by RIG-I (retinoic acid-inducible gene I) and induce a type I IFN response through IRF3, IRF7, and NF-κB (Ablasser et al., 2009; Chiu et al., 2009). RNA polymerase (RNAP) is the enzyme responsible for transcription in eukaryotic cells. RNA polymerase is found in all living organisms because of its importance to the processes of life. RNA Polymerase II: repair, synthesizes precursors of messenger RNA, microRNAs and other types of ribonucleic acid. It mainly transcribes the protein–coding genes into mRNA. RNA Polymerase Function

Apart from that, RNA polymerase 2 transcribes miRNA, snRNA, and snoRNA genes as well. The DNA polymerase cannot initiate the replication process without any help; on the other hand, RNA polymerase can … • RNA polymerase is capable of fulfilling many more functions compared to what DNA polymerase could do. The division of DNA polymerase is generally into three types; on the flip side, the division of RNA polymerase is generally into three types. When the 5’->3’-exonuclease domain is removed, the remaining fragment (M.w.-68,000) retains the polymerization and proofreading activities and is called the “Large (or) Klenow fragment”.

RNA polymerase 2 (Pol 2) is the main type of RNA polymerase involved in the transcription in eukaryotes.

RNA Polymerase Definition. A RNA polymerase (RNAP), or ribonucleic acid polymerase, is a multi subunit enzyme that catalyzes the process of transcription where an RNA polymer is …
