What RNA polymerases is involved in the synthesis of transfer RNA?
Is it RNA III or RNA IV
RNA polymerase three is involve in tRNA synthesis .
Just like mRNA undergo modifications after synthesis similarly tRNA also undergo modifications to convert the pre t RNA to mature t RNA .
t RNA play an important role in translation .

53. RNA polymerases differ from DNA polymerases in that A. RNA polymerases are less effective at proofreading than DNA polymerases. B. only DNA polymerases are processive. C. RNA polymerases do not require a template. B. DNA polymerases use ribonucleoside triphospates as substrates. E. RNA polymerases use deoxyribonucleoside triphosphates as substrates. 54. Which of the following might be a tRNA anticodon for leucine? A. 5-AAC-3' B. 3'-AAC-5'. C. 5'-TTC-3'. D. 3'-UUG-5'. E. 5-UUG-3'. 55. During protein synthesis, ribosomes A. translate mRNA...
Question 3 1 pts The RNA type directly involved in protein synthesis is short interfering RNA. long nc RNA. ribosomal RNA. small nuclear RNA. Question 4 1 pts Which class of RNA molecules is unique to eukaryotic organisms? O transfer RNA ribosomal RNA O messenger RNA small nuclear RNA
1. The virus hijacks the cell, and RNA polymerases produce the complement to the positive stranded RNA genome. We can call these strands negative strands, and they then serve as templates for RNA polymerases to produce their complement. How does the sequence of these strands, the complement to the negative strands, compare with the original viral genome? 2-1. RNA polymerases lack proofreading ability. Define proofreading ability and describe its importance in replication of DNA genomes. a. Why is this a...
Compared to RNA elongation by RNA polymerases, DNA elongation by DNA polymerase requires an additional reaction component. Which is appropriate for fulfillment of this requirement? Select one: a. a primase is needed for the biological DNA replication. b. a short DNA primer is necessary for PCR. c. a host tRNA is used for the synthesis of DNA by viral reverse transcriptase. d. All of these e. None of these
Question 16 1 pts Which is true of RNA polymerases in both prokaryotic and eukaryotic organisms? They have the same number of cofactors in prokaryotes and eukaryotes. They are composed of an analogous a 2ßß'w core. They make copies of RNA from either DNA or RNA templates. There is a single enzyme type per organism. Question 17 1 pts What are E. coli sigma (o) subunits in RNA synthesis? transcription factors receptor proteins RNA polymerases ODNA promoter regions Question 11...
RNA polymerases lack proofreading ability. Define proofreading ability and describe its importance in replication of DNA genomes. a. What advantage might its absence give RNA viruses like SARS-CoV-2? Following protein synthesis, RNA genome and proteins assemble to form virus particles that then bud into the endoplasmic reticulum (ER) lumen and then on to the Golgi apparatus. Next, they are transported via Golgi vesicles to the cell membrane, where they are released via exocytosis. Define ER, Golgi apparatus, and exocytosis,...
What is the target of selection (in bacteria) by streptomycin? Nucleotide synthesis Ribosomal proteins involved in protein synthesis RNA polymerase Cell wall synthesis
Q3. Write different types of RNA polymerases and their corresponding functions in the eukaryotic cell. List three differences between RNA polymerase II and Poly (A) polymerase. What are the roles of Poly A tail in the mature mRNAs?
Describe the roles of RNA polymerases, general transcription factors and regulatory proteins in eukaryotic transcription.
Part A What are three observations that suggested eukaryotic RNA was an intermediate between DNA and protein? Select the three observations. O DNA plays the major role in replication, which allows for sustainable transfer of genetic information. O RNA is transported out of the nucleus and into the cytoplasm where protein translation occurs. Three types of RNA are found in the cell, and all of them are involved in protein synthesis. O DNA is found in the nucleus and protein...
