An Introduction to Molecular Biology/Transcription of RNA and its modification Compare RNA-dependent RNA polymerase. RNA polymerase (RNAP or RNApol), also known as DNA-dependent RNA polymerase, is an enzyme that produces primary transcript RNA. In cells, RNAP is necessary for constructing RNA chains using DNA genes as templates, a process called transcription.NA polymerase enzymes are essential to life and are found in all organisms and many viruses.

How does DNA polymerase work? The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule.ence, DNA polymerase moves along the template strand in a 3'-5' direction, and the daughter strand is formed in a 5'-3' direction. This difference enables the resultant double-strand DNA formed to be composed of two DNA strands that are antiparallel to each other.

RNA polymerase As complex molecule composed of protein subunits, RNA polymerase controls the process of transcription, during which the information stored in a molecule of DNA is copied into a new molecule of messenger RNA.NA polymerases have been found in all species, but the number and composition of these proteins vary across taxa. For instance, bacteria contain a single type of RNA polymerase, while eukaryotes (multicellular organisms and yeasts) contain three distinct types.

- Similarities: Comparisons between bacterial and RNA polymerase II have been performed. Similarity in sequence has been shown between alpha, Rpb3, and Rpb11. Alpha 2 binds beta to form a subcomplex that then binds beta’ that form the core enzyme. Rpb3 and Rpb11 also form a subcomplex with Rpb2. The Rpb3 and Rpb11 show the same fold as the alpha subunit in bacterial polymerase. Beta and Rpb2 as well as beta’ and Rpb1 show sequence homology. The pore in which RNA exits and where NTPs comes into the polymerase are conserved as well (4).

- 1) RNA polymerase unwinds the DNA strand and proceeds to a RNA base with the appropriate DNA base. In bacteria, there is a single type of RNA polymerase. In eukaryotic cells, there are three types of RNA polymerase. RNA polymerase II is specialized for mRNA synthesis.rotein synthesis involves two processes: 1) transcription-the synthesis of messenger RNA from a DNA template and 2) translation: the synthesis of a polypeptide from the messenger RNA sequence.

- 1.DNA polymerase synthesizes DNA while RNA polymerase synthesizes RNA. 2.In contrast with the DNA polymerase, RNA polymerases do not necessarily require the so called primer to start the process and they actually have no proofreading systems. nucleotide can be added to DNA polymerase only on a pre-existing 3’-OH group which requires a primer so that it may add to the nucleotide. The so called primers do contain DNA and RNA base. DNA has the base thymine while RNA has uracil as its base.

Transcription of Messenger RNA (mRNA) from DNA RNA polymerase is the enzyme that assembles the individual nucleotides to create the RNA strand based on the DNA template. The RNA that is built here can actually be one of three different kinds. You may recall that the three different RNA types are mRNA, rRNA and tRNA.

Difference Between DNA POLYMERASE and RNA POLYMERASE 7.Subunits contained in RNA polymerases must unwind the templates of DNA and the DNA polymerases do actually abide the helicase that the double helix may be open just in front of it. 8.Lastly, DNA polymerase is a lot faster compared to RNA polymerase..DNA is double stranded whereas RNA is a single stranded. 5.DNA contains the pentose sugar deoxyribose while RNA contains the pentose sugar ribose. 6.DNA polymerase will be continuous till the work is finally done wherein RNA polymerases will continue but eventually may break in the event it will reach a “stop” cycle.

- The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule.he function of DNA polymerase is not quite perfect, with the enzyme making about one mistake for every billion base pairs copied. Error correction is a property of some, but not all, DNA polymerases. This process corrects mistakes in newly synthesized DNA.

Answers, Chapter 10. Transcription: RNA polymerases b. The templates: DNA polymerase and RNA polymerase use DNA as a template, whereas telomerase copies an RNA template that is part of the enzyme. Reverse transcriptase uses RNA as a template in the life cycle of retroviruses and retrotransposons, but in vitro it can use either DNA or RNA as a template.his mRNA when translated would result in a different peptide than in (b). The complementary antiparallel strands in double-helical DNA do not have the same base sequence in the 5'to 3' direction. RNA is transcribed from only one specific strand of duplex DNA.
