And that means the DNA doesn't actually have to go into the nucleus. It can stay in the cytoplasm of that whole cell and it can replicate and transcribe inside that cytoplasm to form the viral proteins that are needed for the survival of our virus. And one example of such a DNA virus is the pox virus. Now let's move on to the RNA virus. So we saw that the double stranded DNA viruses are much more common than single stranded DNA virus. For RNA viruses it's the opposite.
