During this process the DNA sequence of a gene is copied into RNA.

. Which of the following statements is true for eukaryotic RNA polymerases. 131 DNA and RNA polymerases have several properties in common. Multiple RNA polymerases may transcribe the same template simultaneously.

I Wild-type but not mutant polyA signals instruct the polymerase to stop transcription on downstream DNA in a manner that parallels true transcription termination in vivo. All catalyze the addition of a nucleotide via. RNA polymerase III synthesizes mRNA.

Contents 1 Structure and Function 2 Regulation of rRNA transcription. D DNA from RNA with the help of RNA dependent RNA polymerase. In this way she made the following mutation.

RNA polymerase II synthesizes snRNA and rRNA. Before transcription can take place the DNA double helix must unwind near the gene that is getting transcribed. Using the enzyme helicase RNAP locally opens the double-stranded DNA so that one strand of the exposed nucleotides can be used as a template for the synthesis of RNA a process called transcription.

Translation can only occur after transcription termination. Ob During transcription of a gene RNA polymerase reads only one of two strands of DNA. G The following enzymes are needed to make a cDNA library.

These mechanisms include physical barriers such as skin chemicals in the blood like cytokines and immune system cells that attack foreign. C DNA from RNA with the help of RNA dependent DNA polymerase. A RNA polymerase reads a template strand of DNA 3 to 5.

_____ enzyme is used in PCR technique. All are template directed synthesizing a sequence complementary to the template. Two kinds of DNA polymerase are used.

RNA dependent RNA polymerase RdRp is one of the most versatile enzymes of RNA viruses that is indispensable for replicating the genome as well as for carrying out transcription. DNA-dependent RNA polymerases require specific. 1 Which of the following is true concerning the coding strand of DNA.

Which of the following is true about DNA polymerasea It can synthesize DNA in the 5 to 3 directionb It can synthesize DNA in the 3 to 5 directionc It can synthesize mRNA in the 3 to 5 directiond It can synthesize mRNA in the 5 to 3 direction. RNA polymerase in action. It can synthesize DNA in the 3 to 5 direction.

D RNA polymerase does not require a primer. The correct options are. When the nascent RNA transcript reaches eight to nine nucleotides the polymerase releases the promoter DNA and starts synthesizing downstream DNA sequences.

A RNA polymerase synthesizes 3 to 5. The sigma factor is associated with RNA polymerase during elongation and termination. All the enzymes are needed except RNA polymerase.

The core structural features of RdRps are conserved despite the divergence in their sequences. Using this assay we show the following. Which of the following is true about RNA polymerase.

Correct option is A. RNA polymerase I synthesizes mRNA. Synthesis occurs in a 5 to 3 direction.

The prokaryotic form of RNA polymerase has four subunits capable of transcribing all types of RNA. In molecular biology RNA polymerase or more specifically DNA-directeddependent RNA polymerase is an enzyme that synthesizes RNA from a DNA template. It can synthesize DNA in both directions.

A it is used as a template to make RNA b it is complimentary to mRNA c its sequence is the same as RNA except Ts and Us are switched d it is transcribed in the 3 to 5 direction 2 RNA polymerase does not need which of the following. A Lactose b Galactosidase c Permease d Transacetylase 17. The region of opened-up DNA is called a transcription bubble.

RNA polymerase will transcribe only the exons by skipping over the introns within a eukaryotic gene sequence 2 RNA polymerase will transcribe both DNA strands moving in the 3 to 5 direction for one strand and 5 to 3 on the other 3 RNA polymerase will transcribe both DNA strands but only one RNA molecule will be used during translation 4None of the statements. Innate immunity refers to non-specific defense mechanisms that come into play immediately or within hours of an antigens appearance in the body. None of the above.

Transcription is the first step of gene expression. C RNA polymerase adds ribonucleotides to the 3 end of a growing RNA molecule. RNA polymerase I synthesizes rRNA.

It can synthesize DNA in the 5 to 3 direction. A all four ribonucleoside triphosphates. B RNA from DNA with the help of DNA dependent DNA polymerase.

Recognized by an enzyme that cuts off the end of the RNA approximately 20 bases downstream. Reverse transcriptase to copy the mRNA and E. Coli or phage T4 DNA polymerase for synthesis of the other strand.

The inducing substance in Lac Operon is. The assay requires the use of citrate an inhibitor of RNA polymerase II carboxyl-terminal domain phosphorylation. RNA polymerase 1 also known as Pol I is in higher eukaryotes the polymerase that only transcribes ribosomal RNA but not 5S rRNA which is synthesized by RNA polymerase III a type of RNA that accounts for over 50 of the total RNA synthesized in a cell.

In eukaryotes these enzymes have eight or more subunits that facilitate the attachment and processing of DNA throughout transcription. Transcription termination in eukaryotes depends on. B RNA polymerase has proofreading activity.

C RNA polymerase uses RNA as a template. We can say that the DNA polymerase is faster efficient and more accurate while the RNA polymerase is slower inefficiently and inaccurate. A researcher was mutating prokaryotic cells by inserting segments of DNA.

DNA polymerase DNA ligase RNA polymerase restriction enzymes. Which of the following is true of prokaryotic transcription. Biology questions and answers.

Depend upon the condition. The RNA polymerase enzyme is a large complex made up of multiple subunits 1. The C-terminus of the RNA polymerase must be phosphorylated for RNA synthesis to begin.

15 to 17 bp TATAAT Mutant TATAAT. T7 RNA polymerase is highly processive and can synthesize 200 nucleotides per second and the entire 40-kb genome within minutes Golomb and Chamberline 1974. 1 Which virus type does not need any of its own enzymesa double stranded DNA viruses b negative stranded RNA viruses c positive stranded RNA viruses d retroviruses 2 The protein coat that protects the viral nucleic acid is called _____a an envelope b a membrane c a capsule d a capsid 3 Plus strand RNA _____a can integrate into the hosts chromosome.
