1.) What does RNA polymerase do in transcription? 2.) What is the end product of transcription? Transcription: The information coded in the genetic material is read and transcribed in order to regulate the gene expression. RNA polymerase is an enzyme complex invo...
Briefly, initiation involves the attachment of RNA polymerase to a DNA template promoter by association with transcription, activation, and initiation factors, followed by the acquisition of what will be the first ribonucleotide in the RNA molecule. Elongation involves the sequential addition of ...
RNA polymerase is different from DNA polymerase in that it does not require a primer and it also does not have proofreading activity. The fact that...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough...
If an RNA polymerase does dissociate prematurely, it must start over again at the promoter. 如果一个RNA聚合酶过早分离,它必须在启动子从头开始。 How do the termination signals in the DNA stop the elongating polymerase? 如何终止信号停止延伸DNA聚合酶? For most bacterial genes, a termination signal ...
Grossmann K: Why does DNA-dependent RNA polymerase I from higher plants possess a more complex subunit struc- ture than the enzyme from E.coli? A hypothesis. Plant Cell and Envir 6:1-3, 1983.Grossmann, K (1983) Why does DNA-dependent RNA polymerase I from higher plants possess a more ...
RNA polymerase I (Pol I) specifically synthesizes ribosomal RNA. Pol I upregulation is linked to cancer, while mutations in the Pol I machinery lead to developmental disorders. Here we report the cryo-EM structure of elongating human Pol I at 2.7 Å resolution. In the exit tunnel, we obs...
RNA polymerase III (Pol III) transcribes noncoding RNA, including transfer RNA (tRNA), and is commonly targeted during cancer and viral infection. We find that Herpes Simplex Virus-1 (HSV-1) stimulates tRNA expression 10-fold. Perturbation of host tRNA synthesis requires nuclear viral entry, ...
which allows for intracellular RNA amplification and abundant protein expression. RNA polymerase (T7, T3, or Sp6) is used to transcribe the linear DNA template into mRNA, which is then used to transcribe the mRNA in vitro. The final product should include an open reading frame that encodes th...
(a) What is RNA polymerase? (b) What is its function? What is responsible for the replication of mRNA? What are the role of DNA polymerase and RNA polymerase? What is polymerase chain reaction (PCR) and what impact does it have in DNA and RNA?
Answer to: RNA polymerase has a higher error rate than DNA polymerase. Why is this relatively low fidelity of RNA polymerase not too harmful to the...
