........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.
Retroviruses have Genome consists of single-stranded RNA and these viruses use Reverse transcriptase to make DNA and this DNA is integrated into the host genome so the answer is Retrovirus.

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...
COVID 19 is a positive sense single stranded RNA virus. Which of the following is the case, given this information? It integrates its RNA into a host cell this group of viruses is not generally known to infect humans It requires viral reverse transcriptase to convert its genome into a positive sense RNA strand it has a double stranded genome the genome does not need to be transcribed in order for viral proteins to be produced
Which of the following is true regarding retroviral retrotransposons? A. They encode both reverse transcriptase and an RNA polymerase B. They have directly repeated long terminal repeats at their two ends when integrated into chromosomal DNA C. Their genomic RNA can be translated to produce viral coat proteins D. They leave double-strand breaks in the original donor DNA E. The Alu element in our genome is an example of a retroviral-like retrotransposons
Retroviruses use the enzyme reverse transcriptase to Retroviruses use the enzyme reverse transcriptase to synthesize a hybrid molecule with one DNA stranded base-paired to the complementary RNA strand. synthesize double-stranded RNA. direct the production of DNA from a single-stranded RNA genome. transcribe mRNA from a DNA genome. synthesize sense-stranded mRNA from an antisense RNA genome.
Retrovirus HIV has (+) RNA genome. The virus uses ___________ to make __________. A. viral RNA dependent DNA polymerase, dsDNA B. viral reverse transcriptase, (-) RNA strand
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
Match the term with its correct definition. 1.retrovirus 2. reverse transcription 3. reverse transcriptase 4.Virus Small particles that cannot replicate without a host cell A polymerase enzyme that uses RNA to synthesize complementary DNA strands The virus that contains RNA as its genetic material The process where a virus makes its viral DNA.
RNA polymerase binds to DNA after the double strands have been unwound by helicase. binds to the promoter region and synthesizes mRNA in a 3' to 5' direction. binds to the template strand in the promoter region. transcribes the poly A tail.
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
In rho-dependent transcription termination: the formation of a hairpin in the transcribed mRNA causes RNA polymerase to pause, facilitating termination. rho binds the mRNA, and when it makes contact with RNA polymerase, it assists with the removal of the mRNA from the DNA template. the rho factor binds to the -10 consensus sequence located in the promoter region to terminate transcription. a site within the poly(A) tail is cleaved which signals termination. the 3' untranslated region (3" UTR) is synthesized....
