Question: QUESTION 40 Retroviruses have a +ssRNA as their genome. In order to complete an infection, they must first make a _____ molecule, which they use to direct the synthesis of mRNA. dsRNA dsDNA DNA:RNA hybrid −ssRNA

ssRNA translated into protein by host ribosomes dsDNA replicated by either host or viral DNA polymerase dsDNA packaged into viral capsids Host RNA pol transcribes dsDNA transcribed to make ss mRNA B. Replication of (+) ssRNA translated into viral proteins by host ribosomes (−) ssRNA put into capsids Single (−) ssRNA used as template to make (+) ssRNA by …

Question: (-) ssRNA is transcribed into (+)sSRNA using which of the following?DNA polymerase encoded by the host cellDNA polymerase encoded by the virusRNA polymerase encoded by the host cellRNA polymerase encoded by the virus

Question: SSRNA (single-stranded RNA) and dsDNA (double-stranded DNA) are present in mammalian cells. Why don't our plasmacytoid dendritic cells activate an innate immune response against these self nucleic acids that are necessary for normal cellular function? TLRs have evolved to recognize viral RNA and DNA with exquisite specificity.

ssRNA translated into protein by host ribosomes dsDNA replicated by either host or viral DNA polymerase dsDNA packaged into viral capsids Host RNA pol transcribes dsDNA transcribed to make ss mRNA B. Replication of (+) ssRNA translated into viral proteins by host ribosomes (−) ssRNA put into capsids Single ( − ssRNA used as template to make (+) …

HIV is a retrovirus with a -ssRNA genome. It uses _____ to make DNA copy of its genome that then gets inserted into a host cell's chromosome. Once its DNA is inserted into the host chromosome, the viral DNA is called a _____. When bacteriophage's DNA is inserted into a bacterial cell's chromosome, it is called a _____ which

Question: relevance to other organisms.Which of the following applies to (+)ssRNA viruses?a.)They can be directly translated by the ribosome.b.)They require an additional step before being translated at the ribosome.c.)It requires dsRNA to act as a template.d.)Replication takes place the same way it normally does in the host cell.

More specifically, is -ssRNA transcribed into +ssRNA using 1. RNA polymerase encoded by the host cell or 2. RNA polymerase encoded by the virus or does it transcribe it using dna polymerase? because I thought that if a virus contains -ssRNA then host ribosomes cannot translate it until the -ssRNA is replicated

Question: The genome of influenzavirus is 1) multiple pieces of linear dsDNA. 2) a single circular ssDNA. 3) a single circular SSRNA.

Question: Compare and contrast the following characteristics of ssRNA vs. dsRNA viruses: capsid structure, uncoating (or lack thereof), location/mechanism of mRNA synthesis, and location/mechanism of genomic dsRNA synthesis.
