briefly explain the situation below.
Larger viruses usually have a double-stranded genome, whereas small viruses typically have a single-stranded genome. What reasonable explanation can you offer for this observation?
As a general rule, viruses are not considered to be alive based on several reasons. One such reason is that some viruses use RNA as their genetic material instead of DNA. Which of the five biological themes does this violate? Briefly explain why.
Why do the two types of viruses differ if each has plus configuration single stranded RNA as its genome?
