Answer:

DNA has four nitrogen bases adenine, thymine, cytosine, and guanine and for RNA instead of thymine, it has uracil. Also, DNA is double-stranded and RNA is single-stranded which is why RNA can leave the nucleus and DNA can't. Another thing is that DNA is missing an oxygen.

Latency means that the virus will not be actively dividing for a certain period of time which means signs and symptoms related to viremia and direct action of the virus will disappear. This does not mean that the patient is cured, but the disease will soon be active again anytime, especially if the patient will enter a time of immunocompromise.
