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. So although we do have some examples of double stranded RNA viruses, the single stranded RNA viruses are much more common. So RNA viruses basically inject their RNA molecules, the RNA nucleic acids into the cynoplasm of that whole cell. And once inside the cytoplasm, the RNA can be used to synthesize the proteins or the RNA can be used to basically transcribe into mRNA and then that viral mRNA can be used to form the proteins needed for the virus to actually survive.
