Previously it was thought that RNA virus replication took place in the solube portion of the cytoplasm of cells. We now know that this is not the case and that the replication complexes are located on specific structures in host cells. Briefly EXPLAIN what structure or structures in the cell are involved and how viruses use them to replicate their RNA genome.
Homework Answers
Their is diffrent type of rna
genome of virus are present which are categorized in positive and
negative sense.Negative-sense ssRNA viruses have their genome
copied by an RNA replicase to form positive-sense RNA. This means
that the virus must bring along with it the RNA replicase enzyme.
The positive-sense RNA molecule then acts as viral mRNA, which is
translated into proteins by the host ribosomes.

Which among A-D is false regarding most DNA virus infections and most non-retroviral RNA virus infections? A. Once inside the host cell, RNA virus replication usually (though not always) occurs completely in the cytoplasm. B. The genome of DNA viruses generally must enter the nucleus of the host cell they infect. C. A (+) sense RNA strand produced by an RNA virus could serve as an mRNA and be directly translated into protein. D. DNA viruses typically are assembled in...

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

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...
