Answer:
Double-stranded DNA
Explanation:
If a virus requires to transport its genome in the nucleus to produce viral protein then the viral genome content must be DNA. This DNA of the virus will use the RNA polymerase of the host cell and will first convert into mRNA in the nucleus.
Then the mRNA of the virus will come out of the nucleus because the protein synthesis takes place outside the nucleus and in the cytoplasm. So in the cytoplasm by using host translational machinery the viral mRNA will code for viral proteins. So the correct answer is double-stranded DNA.

Then they leave the cell.
The sodium diverts in the cell layer have receptor locales for acetylcholine.
They are an invasive species, they kill off our beautiful salmon and other fish that we need to keep a good flow of fish exports and money flowing into our state. It's important to keep that balance so that both the pray and they predator in the lakes don't all die out.
