Influenza virus contains RNA not DNA. Influenza tricks the human nuclear envelope into lettting in viral nucleotides. How does that happen? What are the steps? Does influenze reverse transcribe its RNA? If so is this done inside the virus, and inside or outside the nuclear envelpe? Can the virus take-up other RNA and make it part of its own genome and get the incorporated RNA into the nucleus as well, either as RNA or as DNA?
It would mean the difference between any virus and the virus which only infects a particular host. Or why we could have a carrier.
The virus tricks the cell by interactions with the receptors on the outside. This means the cell takes the RNA (the same with DNA) and when it is inside the nucleus it makes new virus. Sometimes it gets digested and there is no infection. Electroporation makes sure the DNA or RNA is taken by the cell. (Bacteria at least). It turns to evolution when virus takes if not a copy, some of the genes and reinfects again.
Reverse transcriptase and similar enzymes to this one reverse flips DNA to RNA and viceversa. They normally take the DNA or RNA into vacuoles or by themselves to the nucleus. There are pores which the material is extracted, but the RNA does not need anthing. They may not replicate. They may take hours or days (lysis and lisogenic cycle).
