How do DNA polymerase and RNA polymerase differ? DNA polymerase is quite different from RNA polymerase. DNA Polymerase synthesizes a DNA strand and used in DNA replication while RNA Polymerase is used during transcription to synthesize the mRNA strand. In contrast with the DNA polymerase, RNA po...

RNA polymerase II RNA polymerase II of Saccharomyces cerevisiae consisting of all 12 subunits. RNA polymerase II (RNAP II and Pol II) is an enzyme found in eukaryotic cells. It catalyzes the transcription of DNA to synthesize precursors of mRNA and most snRNA and microRNA.A 550 kDa complex of 12 subunits, RNAP II is the most studied type of RNA polymerase. A wide range of transcription factors are required for it to bind to upstream gene promoters and begin transcription.t catalyzes the transcription of DNA to synthesize precursors of mRNA and most snRNA and microRNA.

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.

An Introduction to Molecular Biology/Transcription of RNA and its modification RNA is transcribed in the nucleus; processed, it is transported to the cytoplasm and translated by the ribosome. At the end of its life, the mRNA is degraded. In transcription, the codons of a gene are copied into messenger RNA by RNA polymerase.In simple word or formation of RNA from DNA is known as transcription.This RNA copy is then decoded by a ribosome that reads the RNA sequence by base-pairing the messenger RNA to transfer RNA, which carries amino acids.NA is transcribed in the nucleus; processed, it is transported to the cytoplasm and translated by the ribosome.

- RNA polymerase. Rna polymerase (RNAP or RNApol) is an enzyme that is responsible for making rna from a dna template. In all cells RNAP is needed for constructing rna chains from a dna template, a process termed transcription.na polymerase enzymes are essential and are found in all organisms, cells, and many viruses.

Figure 3: RNA polymerase at work. RNA polymerase (green) synthesizes a strand of RNA that is complementary to the DNA template strand below it.fter the transcription of DNA to mRNA is complete, translation — or the reading of these mRNAs to make proteins — begins. Recall that mRNA molecules are single stranded, and the order of their bases — A, U, C, and G — is complementary to that in specific portions of the cell's DNA.

- The RNA to which the information is transcribed is messenger RNA (mRNA). The process associated with RNA polymerase is to unwind the DNA and build a strand of mRNA by placing on the growing mRNA molecule the base complementary to that on the template strand of the DNA.

Translation: DNA to mRNA to Protein During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.© 2013 Nature Education All rights reserved.n the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.

DNA Transcription Proteins can be manufactured in large quantities because a single DNA sequence can be transcribed by many RNA polymerase molecules at once. DNA transcription is a process that involves transcribing genetic information from DNA to RNA. The transcribed DNA message, or RNA transcript, is used to produce proteins.

Replication vs. Transcription In transcription, or RNA synthesis, the codons of a gene are copied into messenger RNA by RNA polymerase. As opposed to DNA replication, transcription results in an RNA complement that includes uracil (U) in all instances where thymine (T) would have occurred in a DNA complement.eplication is the duplication of two-strands of DNA. Transcription is the formation of single, identical RNA from the two-stranded DNA. Enzymes. The two strands are separated and then each strand's complementary DNA sequence is recreated by an enzyme called DNA polymerase.

How is mRNA made, what is this process called? Best Answer: Transcription. DNA---Transcription---mRNA---Translatio... In transcription DNA is unzipped and the enzyme RNA polymerase runs along the template strand of the DNA. The template strand of DNA can be identified by finding the nucleotide sequence T A C at the 3’ end (you can see this on your template strand).RNA, or messenger RNA, is generated by reading a strand of DNA. RNA polymerase (an enzyme that specifically makes mRNA) moves along the strand of DNA and joins complementary strands (in RNA, the complement to adenine is uracil instead of thymine). mRNA is produced only for the gene that is being read at that time.

Messenger RNA (mRNA) is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.
