What is the role of DNA polymerase in transcription?

What is the role of DNA polymerase in transcription?

RNA polymerase (green) synthesizes RNA by following a strand of DNA. RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription.

Is DNA polymerase used in transcription or translation?

Making a Protein, Part 2: Translation

Is DNA polymerase required for eukaryotic transcription?

As previously discussed, distinct RNA polymerases are responsible for the transcription of genes encoding ribosomal and transfer RNAs in eukaryotic cells. All three RNA polymerases, however, require additional transcription factors to associate with appropriate promoter sequences.

Is DNA used in transcription?

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template.

What is the difference between DNA polymerase and RNA polymerase?

The main difference between DNA and RNA polymerase is that DNA polymerase produces a double-stranded DNA molecule during polymerization whereas RNA polymerase produces a single-stranded RNA molecule during transcription.

What is difference between transcription and translation?

Hint: Transcription is the process of copying a gene’s DNA sequence to make an RNA molecule and translation is the process in which proteins are synthesized after the process of transcription of DNA to RNA in the cell’s nucleus. Translation synthesizes proteins from RNA copies.

What happens if RNA polymerase is not present?

Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. This process, which begins with the transcription of DNA into RNA, ultimately leads to changes in cell function. Changes in transcription are thus a fundamental means by which cell function is regulated across species.

What do you need to know about transcription and translation?

A DNA template b. A primer c. Ribonucleoside triphosphates d. RNA polymerase e. All of the above are required for transcription. b RNA polymerase is a. an RNA-directed DNA polymerase. b. an RNA-directed RNA polymerase. c. a form of RNA. d. a ribozyme. e. a DNA-directed RNA polymerase. e

How are restriction enzymes used in DNA transcription?

Restriction enzymes recognize specific sequences, mostly 4-6 bp, in the DNA and cut it into fragments by breaking the phosphodiester linkage between two successive nucleotides of DNA. This makes option A incorrect as transcription does not involve breaking the phosphodiester bonds of DNA molecule.

What do you need to know about RNA polymerase?

RNA polymerase e. All of the above are required for transcription. b RNA polymerase is a. an RNA-directed DNA polymerase. b. an RNA-directed RNA polymerase. c. a form of RNA. d. a ribozyme. e. a DNA-directed RNA polymerase. e DNA is composed of two strands, only one of which typically is used as a template for RNA synthesis.

How are RNA molecules synthesized in the process of transcription?

In the process of transcription, a. a DNA molecule is synthesized from an RNA template. b. ribonucleoside triphosphates are assembled into an RNA molecule in the absence of a template. c. an RNA molecule is synthesized from a DNA template.
