During transcription, RNA Polymerase binds with upstream of the gene that is to be transcribed into mRNA. This causes the double helix shape of the DNA to unwind. Then, RNA Polymerase uses the template strand of the DNA as guide and synthesizes a complementary mRNA strand using ribonucleotides. Basically, without RNA Polymerase, mRNA would not be synthesized.

The reaction catalyzed by DNA polymerase is?
There are different types of DNA polymerase depending if it's from a eukaryotic or prokaryotic cell each performing specific tasks. Basically DNA polymerase catalyzes the formation of a polymer, a DNA strand, from many monomers, deoxyribonucleotides.
What is a polymerase commonly used for?
Polymerase are best know for their role in DNA and RNA replication. The polymerase reads the DNA or RNA strand as a template to synthesize a new strand.
What is the role of the DNA coding strand?
It helps position RNA polymerase correctly at the promoter.
Why taq polymerase is thermostable?
Taq Polymerase is an important enzyme component involved in the PCR reaction. Its A DNA polymerase and its role is to elongate the growing strands of DNA during the extension process. Since the Extension process in a PCR works at a temperature which a human DNA polymerase cannot remain active, the Taq polymerase obtained from Thermus aquaticus (living in the hot springs) are used and hence these enzymes are thermo stable.
What is the role of the enzymes in cloning?
The role of arestriction enzyme is to remove the intronsto make a mature mRNA, so that the new mRNA codes for the making of a single protein. The restriction enzyme will only leave the exons to make the mRNA more shorter, and therefore easier to insert into plasmids
What is the explanation for the Role of RNA polymerase?
Basically, RNA polymerase's role is very similar to that of DNA polymerase. RNA polymerase is an enzyme that is used during transcription in the nucleus. Similar to DNA polymerase, RNA polymerase codes for the complementary nucleotides to a DNA strand. Instead of thymine though, uracil codes with adenine. This coded mRNA strand then travels from the nucleus to the ribsome where translation occurs - the result is protein made from an amino acid chain. To answer your main question - RNA polyermase adds the complementary nucleotides to the DNA strand using uracil instead of thymine. hope that helps :)
What do the promoter region do in the DNA translation?
The promoter region has no role in translation. It is the site where RNA Polymerase binds to initiate transcription. Basically, talking about bacteria, a protein called sigma70 binds to the promoter and recruits the RNA Polymerase enzyme. After the RNA Pol is recruited, the sigma70 factor is released and RNA Polymerase synthesizes the complementary mRNA from the DNA that is being transcribed.
What is an important role of RNA during transcription?
RNA play a vital role in Transcription, basically when DNA provide an information about synthesizing amino acid then Transcription occur. In transcription DNA unwind and mRNA synthesize through RNA polymerase. Intros are removed which are non coded region of DNA in nascent mRNA through splisosomes, and only Exon remains a coded region of DNA. In simple DNA dictates to mRNA about specific protein structure.

RNA Polymerase is an enzyme that synthesizes the formation of RNA from a DNA template during transcription.
What is role of mRNA during translation?
It provides the code for the protein.
What is the role of the DNA coding strand?
It helps position RNA polymerase correctly at the promoter.
What is the role of tRNA in protein sythesis?
The transfer RNA brings a specific amino in the cytoplasm acid to the ribosomes where they are linked together into the growing polypeptide chain.

The role of the mRNA molecule in a cell is?
To transfer codes for the cell's proteins.
What role does the structure of RNA and DNA play in protein synthesis?
mRNA. tRNA,
