Option C
RNA dependant RNA polymerase
Most of RNA viruses have RNA as genetic material and to synthesize their structural components, if is possible by the RNA polymerase which read their self RNA and proceed for transcription. So the RNA polymerase should depend on RNA genome.
Question 29 Which of the enzymes below would nearly all RNA viruses have? DNA-=dependent DNA polymerase...
For ss (+) RNA viruses, which protein is responsible for copying the genome? 1 the ribosome 2 the RNA-dependent RNA polymerase (RdRp) 3 DNA-dependent DNA polymerase 4 the reverse transcriptase
Which of the following enzymes are needed for Transcription to occur? O A. RNA polymerase OB. Reverse Transcriptase OC. DNA polymerase OD. DNA ligase O E. Restriction enzyme Reset Selection Mark for Review What's This?
In order to replicate RNA viruses such as COVID19 must first be converted to DNA. What viral enzyme would be an attractive drug target to inhibit this step? A. COVID spike protein B. RNase C. DNA polymerase D. Reverse Transcriptase.
Incorrect Question 6 0/0.5 pts Why must dsRNA viruses package an RNA-dependent RNA polymerase (RdRp) inside their viral capsid? Because all RNA viruses package an RdRp. Because the converts the ENA DNA so it can be translated by stroom Because that in the genome cannot functie ASTRA GERNArtes dontactly Preando
a,b and d please 1. (6 pts) The genomes of viruses are diverse. For animal viruses, they often encode and bring own polymerases to the infected host cell for viral replication. a. (1 pt) Viruses with single-stranded RNA as their genome for which the nucleotide sequence is the same as the viral mRNA are said to be viruses. (Circle one best answer.) A) plus-stranded; B) minus-stranded; C) mRNA-like; D) complete; E) defective b. (1 pt) A virus is an obligate...
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
help Which of the following enzyme is essential in PCR? RNA primers taq- polymerase • RNA polymerase reverse transcriptase ORNA dependent RNA polymerase
........have genomes that consist of (+) strand RNA. Instead of RNA polymerase, they package a reverse transcriptase, which transcribes the RNA into a double-stranded DNA. The double-stranded DNA is then integrated into the host genome, where it directs the expression of the viral genes.

(Circle all that apply) (+) ssRNA viruses dsDNA viruses SSDNA viruses Θ ssRNA viruses Which viruses must have a gene for a viral RNA polymerase in order to replicate? (Circle all that apply) (+) ssRNA viruses dsDNA viruses SSDNA viruses Θ ssRNA viruses
Which statement among A-D is false regarding non-retrovirus RNA viruses? A. they possess RNA-dependent RNA polymerase B. the genome of single stranded (+) RNA virus like West Nile virus, can serve directly as mRNA C. during the multiplication process inside a host cell, a single stranded (-) RNA virus must go through a (+) RNA stage before forming progeny phage D. such viruses can produce a provirus form in the host E. None of A-D is false, they are all...
