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.
 
        
             
        
        
        
Answer:
compression and rarefaction
Explanation:
This kind of wave is called a longitudinal wave and an example of such a wave is a sound wave.  The center of compression can be analogous to the top of a crest of a transverse wave while the center of the rarefaction would be analogous to the bottom of the trough of a transverse wave.
